Some projects that I would like to complete as a hobby are:
- better version of omxplayer, possibly with RTMP support (streaming)
- decent SNES emulator, I have chosen Snes9x so far (see related rPi forums discussion thread)
- 10x10 LED matrix controller, this will be more a hardware challenge than software challenge
I will document the progress and of course properly publish the projects in a genuine open-source way.
