Hola, I was in a small party where people sang on PS2 (Singstar game). Then suddenly it occured to me that, actually it would be completely feasible game to play with N900: You can plug it on TV and you could sing holding the device on hand like microphone. Of course it has only one microphone and there is a LOT to do before anything like Singstar is possible, but still. With tunewiki, your own songs, some volunteer work/songscripting and simple sound detection it is perhaps doable. What do you think? Anyway the idea is now on the open.
