Way back when, I wrote a version of Cosmic Wimpout for the palm.
Link: CWimp on GitHub
Maybe someone will want to work on it. Or maybe I’ll buy a new palm one of these days. I heard rumors that Palm runs Linux or something like that.
UPDATE 2011-03: I have moved it to GitHub instead of hosting it locally. This project is really dead, but if it still works for you, great!
