This is interesting - taking the colors in a movie poster and reducing them to bar codes. Do they make you want to see the movie more than the actual movie poster?

Oh my! How interesting!! :D Toy Story looks most appealing at one glance, but since I like horror, I should be looking for the most dreary barcode right? :P But I don't feel like I like dreary barcodes. :(

How do they do that effect?
