Hey, great job on the application! I haven't had the chance to make some real photos with it yet, but it ofcourse works on my Canon 350D! I was thinking about a cool feature for pyKake: an Interval-o-meter! I'm no programmer but I think it wouldn't be hard to make. Just set the interval to a specific time (like 1 minute), and let the the N900 send out a signal every minute. Keep this going for 25minutes and you've got a one second timelapse! I think this would be a really useful feature, and if I'm not wrong, not a hard one to implement
