well, like i said, it's like Smilebasic. you make an account on it, and you can animate to make games and stuff. you can add music and many things. it's very random. :D
Scratch is useless! They made me use it at school, and it was horrible! All you do on it is drag blocks and press play. The puzzels aren't hard at all! It even tells you how to solve them! But... that's just my opinion.
