Using custom blocks, I can draw any script using only the pen. This took a lot of work, and I have not yet beta tested everything. Feel free to figure out the script syntax and test it out yourself!!! So, if you don't understand what this does, the draw script block can draw any script, although not all are perfect... (I am working on it) Don't want to figure out the syntax yourself? Sorry, I am too lazy right now to put it here. :P
This is based off of a cool project which I think I favorite-d. EDIT: Found it! This project is based off of http://scratch.mit.edu/projects/11748014/ Also, there is a new version! (Just click on my profile!)
