I'm writing a Scratch to Scratchblocks (and possibly also 'C') converter - I need to exercise all Scratchblocks to test it. See inside. This project doesn't actually execute anything, and in fact I have no idea what will happen if you try to run this, but it won't be anything good! I've tried to include all blocks, and if I find any constructs that break my converter I'll add them as a regression test.
