there's also tylerwm (google it). I'm currently writing my own with a totally different approach.

Have you tried tylerwm? It looks like what I desperately want on OS X, but every review I've read suggests it's too unstable to use. I'm nervous about paying $10 for something I'm not sure will work.

I tried tylerwm about three months ago and it was quite flaky. Sometimes it would re-arrange windows while I'm typing. Turned it off an hour later.

Save your money, it's unusable (windows jump around randomly).
