Retina lollipops

A candy store at the local mall had the most amazing wall of colorful lollipops, and I thought it'd make a wild desktop image for a retina iMac. As I snapped the pic on my iPhone, it took a bit of upscaling to reach 5120x2880, but I think it still looks fine; here's a small-scale version:

I also thought a tunnelized version would be interesting; here's how that came out:

I have these in my normal "rotate random every 15 minutes" cycle, and still get a kick out of the lollipops when they get chosen.



A unique lava lamp time-lapse

We occasionally take our kids to a local place, Big Al's, which is one of those bowling/arcade places that give out tickets as rewards from the arcade games. Being good parents, we too sometimes play the games (you know, to spend time with the kids…yea, that's it). Over the years, we amassed quite a bunch of tickets, but weren't quite sure what to spend them on.

The last time we were there, I was smitten by a lava lamp, similar to this one, but ours has a black base and blue "lava." I don't know why (childhood flashback?), but I decided some of our points cache would go to this mesmerizing but otherwise useless device.

When I got it home, I was surprised at just how long it takes to warm up: It can take nearly an hour before any "lava" starts flowing, and about two hours before it really looks like a traditional lava lamp. During the first hour, though, the melting wax in the lamp makes some really cool abstract bits of art, as seen in the photo at right.

I thought this might make a neat time lapse, so I set out to record it with the iPhone. My first attempt failed, due to the iPhone's auto-adjusting time-lapse feature. Because the lamp takes so long to get going, the gap between frames winds up being quite long. Long enough that when stuff does start happening, the iPhone's time-lapse gaps are too wide to make for an interesting video.

I needed another solution, so I headed to the iOS App Store to see what was available…

Cheap fireworks in slow-mo are oddly compelling

I'll be out of town on the Fourth of July, so the kids and I did our little fireworks celebration last night. This being Oregon, we stuck to what we could legally buy, which basically means nothing that can fly or explode. For grins, I set up my iPhone on a tripod, and shot some of the fireworks in slow-mo mode. The result was much better than I was anticipating…

That's about a minute's worth of one of the larger fireworks. You can download that one (1280x720, 96MB), or if you want, download the full seven-minute version. Be aware: If you're on a metered connection, the big version will set you back 671MB!



Send your Retina iMac’s desktop to deep space

Last week, I used the just-released Hubble Space Telescope images of the Andromeda galaxy to create a couple of desktop images for my Retina iMac. I liked the results so much that I spent some time collecting other suitable images from the Hubble site, and then cropping and/or scaling them to create interesting high-res desktop images. (I used Acorn for all the edits; it had no troubles, even with TIF images as large as 20,323x16,259!)

The end result is a collection of 50+ Retina iMac-sized (5120x2880) desktop wallpapers, courtesy of the Hubble Space Telescope. Here's the full collection:

Tip: If you click on the caption below the image, you'll be taken to the source page on the Hubble telescope site where I found the image.

There are at least two versions of nearly every image—one or more where I cropped out an interesting area of the photo at 5120x2880, and one where I scaled down and then cropped as needed to get as much of the full image as possible.

There are three ways to get an image (or all the images):

Method One: One at a time

  1. Command-click on the image (anywhere other than on the navigation arrows) you'd like to download. This will create a new background tab (in Safari, Chrome, and Firefox, at least), loaded with that image's high-resolution page on my OneDrive.
  2. At the top of the page you'll see a Download icon and text; click there to save the file to your Mac.
  3. Repeat for each image you want, and then organize as you wish, and set them up as rotating desktop images.

Method Two: Another way to get one at a time

Open the full folder on OneDrive, and browse/download directly from there. Click on any image, then click the Download icon to download the selected image to your Mac.

Method Three: Gimme the full set!

If you want all 54 images, just download this zip file from OneDrive.

It’s snowing…in slow motion!

It's just started snowing here in central Oregon, so I shot a bit of slow motion snowfall. The end result is very oddly mesmerizing (open the video in a new window to see it at full size):

The snow looks like some fake Hollywood effect when seen in slow motion. But hey, it's falling, it's sticking, and the kids may get a white Christmas after all!

I hope you and yours have a wonderful holiday…I'm outta here to go play in the snow!



Fake fire … enhanced

To make our winter-air-blocked non-functional fireplace more visually engaging, I printed a huge fireplace image across multiple pages, and taped them to the fireplace blocker. The end result was usable, but definitely not professional:

So I set out to find a shop to print a 36"x48" poster of the huge image. And because this was clearly an optional project, I wanted to do it as cheaply as possible. After much web searching, I found Poster Print Factory. Their online poster creation tool was easy to use, and the cost ($35 including shipping) was the lowest I found by at least $10.

It took about a week, but the poster arrived and the quality is fine. It's printed on relatively thick stock, and the image itself looked stunning. So now, our artificial fire has been enhanced by a high quality poster overlay:

So much nicer to look at than the silvery surface of a piece of foam insulation! Anyway, if you're looking for some inexpensive poster-sized prints, I was happy with what I got from Poster Print Factory.



Span one large image across multiple printed pages

I was looking for a way to print a large image across multiple pages, so I could make my own do-it-yourself poster-size printout. By way of background, I wanted to print a huge virtual fire, to cover a piece of insulation we put in front of a drafty fireplace in the winter. (We don't like to burn wood, so the fireplace goes unused, but staring at a piece of shiny foam insulation all winter isn't all that interesting.)

Conceptually, this seemed pretty easy: find a huge image, open it in some app that handles images, and print. What I found is that doesn't work, at least not in the apps I had at hand (Acorn and Preview). After some web searching, I stumbled across an odd but effective solution: use Excel.

Open a new blank Excel workbook, then select Insert > Photo > Picture From File, and select your massive image. Now when you hit Print, you'll see the output spans multiple pages. I used Page Setup to select a borderless US Letter size, and printed out 16 pages of a roaring fire.

After some cut-and-tape operation, the drafty fireplace's insulation became more visually appealing:

Note that this was a "proof of concept" operation, so I printed in draft mode (hence the vertical striping on the printout) and wasn't overly careful about lining up the pages. I had originally planned to print the final version on glossy photo paper, but instead opted to buy a 36x48 poster-size printout from an online vendor. (I haven't yet received the print, but when I do, I'll post about its quality. Until then, though, I don't want to link to the vendor, as I don't yet know what I've bought.)

I knew Excel could do a lot, but I never thought to try it for printing huge images across multiple pages.



Wallpapers: iPhone 6

Once I had my iPhone 6 syncing, it was time to get to work on my home and lock screen wallpapers. I have made these for every iOS device I've owned—here's the full collection.

My home screen wallpapers feature a bar to highlight the paging dots, and are typically "low noise" to make it easy to see icons and text. The lock screen wallpapers have no such restriction, and include a little bit of everything.

These wallpapers are 750x1344 pixels in size, and are designed for use on the iPhone 6, as that's what I have. (If you use a Plus, and really like an image or two, let me know and I can make one for the larger phone.) Note that the images shown in the image sliders below (hover and click to cycle) are low-quality 180x320 JPEG representations of the actual photos; to get the high-quality images, download the entire bundle [24MB] and install only those you wish to use.

Home Screens (16)Lock Screens (52)

Note: Due to a quirk in iOS 8, you need to use these steps when installing one of my home screens, otherwise the nav bar (the bar that shows the page navigation buttons) won't be located in the right spot. Here's how, assuming you're in the "Choose a new wallpaper" section of iOS:

  1. Tap the desired home screen icon to see the full-size version.
  2. Disable Perspective Zoom. (It won't work right with the navigation highlight row I use.)
  3. Pinch and zoom out so the image is at it's 100% size.
  4. Now drag the image up and let it bounce—this is the critical step.

If you've done the above steps right, then you'll see quite a few pixels of the nav bar above the Perspective Zoom button (top image). If you haven't done it properly, then the nav bar will barely clear the button (bottom image).

Given the images are the same resolution as the screen, I have no idea why this happens…but it does, and this is the only way to make sure the nav bar winds up where you want it.

A visual guide to iPhone screen resolution over time

While I was working on some iPhone 6 lock and home screens, I paused for a few minutes to put together this visual guide to the iPhone's changing screen resolution over the years (click to zoom):

Both the inline and zoomed image above are smaller than 100% scale, of course. But if you'd prefer, you can check out the massive full-size version. Be forewarned, this is a 3628x2188 pixel photo, and it's 1.7MB in size.

For the curious, the original photo was taken at Great Sand Dunes National Park and Preserve, at roughly this spot, looking north-ish.

When viewed in this comparative manner, the iPhone Six Plus' resolution really stands out—there are a ton of pixels on that gorgeous screen!



Dropbox shows iPhoto what simple really means

Note: Dropbox—sadly—removed this feature in July of 2017, so don't even bother reading any further.

Did you know that Dropbox lets you create photo albums? No? Me neither, until this morning, that is. And it turns out, it's incredibly easy to do:

  1. Copy or move a folder of images into your Dropbox folder. Choose any location within the Dropbox folder that you wish; I set up a Photos folder to hold slideshows.
  2. Open the Dropbox web site, and sign in to your account.
  3. Navigate to the folder you just uploaded, right click, and choose Create album.
  4. Click Share album, then copy the link or directly invite those you'd like to see the album.

That's it, your'e done. The only time-consuming portion of the process is uploading the images; creating and sharing the album takes almost no time at all. That's about as simple as it gets.

Now assume you want to do the same thing using iPhoto: create a web-based slideshow of images for anyone to see via a shared URL. Sure, you could use iCloud's Photo Stream, but that's not a web-based solution. Instead, you'll need to use File > Export in iPhoto, and either create a Web Page or a Slideshow. Slideshow is really misnamed, though, as what it really creates is a movie of your images. So Web Page it is.
