I think I will . .
. .do a game. Perhaps.
My bet on the winning theme is ‘two colors’, because the theme I like the least always wins so far :).
Programming will be in ActionScript or Java.
Graphics: depends on what I’ll do. ASCII, MyPaint, Flash.
Sound: I recently acquired a C64II so I think I will use that for music (live recording). Also guitar, PC synth, mobile phone piano app, whatever makes sound. And the microphone and Audactity for effects.
