I got myself the sourecode from drnoksnes, but it is written in C, so the methode of keyreading could be very diffent en not easy to do in Python. I will take a look at it.

About the fullscreen: I hope pcekper will resume his work on his N900 version of gngeo. I don't think he made his code public. Restarting his work by mixing the code from the N800 and "general" version would mean re-doing things. I can code a little C, but such low-level programming will be too hard (and consequently time consuming) for me I'm afraid.
