It happens every once in a while. You are making something on Alice that you think would be better in 2D than 3D, and you don't know what to do. You try Googling it, but nothing comes up. If you want to make a 2D animation, then you need Scratch.

Normally, when you choose to download Scratch, you have to sign up for an account, but if you are one of those people that doesn't want to give away information about yourself, I have made a bypass link for you. I am on the Scratch Forums too, and I go under the username "David_B" (without quotes). I hope to find you there.
