For more colors, check out Version 2: http://scratch.mit.edu/projects/ManaUser/2861467 This creates tartan patterns, like those used on Scottish kilts. I was impressed by how such interesting designs can be created from simple instructions like "K2 B10 G10 R2 A6", so I thought it would be fun to make my own tartan generator in Scratch. Unfortunately, Scratch's screen size is a bit small for most traditional tartans, but it's still fun to play around with.
