I've been thinking about ways to use the crawlers that I wrote last week. Some ideas that I had were maze generation (it is out because the mazes are actually pretty lame), tile texturing (the tiles have to be really large for it to make sense), and random entity movement (not sure why this would ever be useful). Then I noticed that all of the negative space paths always touch the outside border, so if I spawned crawlers on the corners of the space I could fill in the pattern every time. So then I decided to try them with scene transitions and I really like the look. It would only work in games with a certain style and the speeds need to be adjusted because the transitions are too long now, but I'm happy with it.
