I'm Lefty, I use Scratch to storyboard Java projects, and see how far I can push simple concepts.
Most of the things I share will be a complete mess, so don't worry about it.

-AI for a sprite that wanders, navigates and chases
-A randomly generated RTS
-A crappy Binding of Isaac clone
-A Halo/Age of War inspired game
-A really big RPG with an engine for making maps
