Substring explorer

u/Agnes

Every frame, this tries to find a random substring of length L that appears somewhere in the member variables of the Javascript canvas object c. If it finds a match, L is increased by one.
u/Agnes

I think this crashes if W.length gets too long but I don't think it's ever going to get much further than 5 in the lifetime of the universe so we're fine.
