When I saw "Official iPhone Lego App" in my mailbox today, I got instantly wet. Then I checked it out in the iTunes App Store, and my dreams were destroyed. But when I tried it, I loved it anyway.
But then again, I'm a Lego sucker. Big time. So, while the Lego Photo application is obviously not my dream virtual Lego construction app, I definitely like it very much. It's elegant, well designed, and the results—which convert your images into pretty 1x1 Lego mosaics—are pretty.
I wish they add an option to give you a list of bricks needed to complete the mosaic in real life. [iTunes—Thanks John]
