Scratch

I recently posted a project Pen Lab 3.0, with lots of cool features. You can draw with pen, obviously, there's an eraser, and also stamps. There's celebrity stamps, so you can draw on their faces or use facial hair stamps to "customize" them. You can change music
(The options are Fireflies, Firework, and Party Rock). It's really fun and alot of work went into it so please check it out and love it!
