so far i only have one, but i coded it to be easy to add more. this is a riddle (well, that's what they call it) i found online. you have to figure out what the pattern is. i just quickly threw this together so the programming isn't very good. it is extremely hard to read as well because of the unrolling of loops (4-5 times each). i wish i knew why bad programming is better in scratch... ihope they change that for scratch 2.0. either way, postif you got it without looking at the answer (i had to look...), and please check out my other projects.
