Kine over on the JME Forums is working on a stunning looking racing game named Bolidz. Extremely abstract looking backdrops look like it they add to the feeling of speed. It appears to be quite early in development but I can't wait to see where this one goes.

HHexen is a work in progress over on the JMonkey Forums. The author describes it as "a little game to mess around and kill some bad guys" which sounds just about perfect to me. The procedural dungeon generation looks particularly interesting. Note that although the game looks like Hexen/Heretic it's not intended as remake.
