We recently toured Nathan Sawaya's The Art of the Brick at OMSI, our local science museum. I had heard about this show, and seen pictures, but they don't do it justice…so here, look at some of my pictures which also won't do it justice. [View on Flickr]
Part of the reason photos don't do the ehxibit justice is the lack of sense of scale—further accentuated in my photos due to the lack of reference points. Most of these things are quite large; the human figures are all life size (or bigger). The Easter Island head is maybe 8' tall, the Whistler's Mother figure is six or so feet long, etc. Each piece has a descriptive card that includes the total number of Lego pieces used. As you'd expect, it's a lot of Lego!
If you're in the Portland area—or The Art of the Brick is coming to your town—I highly recommend a visit. You don't even have to like Legos; the art is just amazing…even without considering it's made of Lego bricks.
