This is probably my first vaguely decent project. Aside from the vector hand. That was amazing. Anyway, click the green flag, watch the magic, press space if you want to start over. Holding space is pretty cool, especially in turbo mode. If you want, look at the code and mess with the values a bit. They're pretty cool. UPDATE: Although it's rare, there are still chances of a glitch where two lines generate in each other. I have no idea how to stop this. Dangit.
This was inspired by a fellow called Tim Holman. He isn't on scratch as far as I know, but just look him up and you can find some really creative web design and some cool pen stuff. UPDATE: Bug fixes with the cloning mechanics, added in pen shade junk for more painty paint variety. UPDATE: Still messing around with the shading values. Possibly final.
