Sketch is fun website (click to open) where you can see how others draw. Someone draws a picture, and the site animates it so it is drawn before your eyes. Like magic! It also has tools to draw your own, and it's really simple. Lots of colors too. Give it a whirl!
You have to add your name to access it, so check with your parents. I just kept hitting "random" and looked at many beautiful and funny drawings.
