I was checking out the results from Assembly 2006 and I noticed they now have an game competition as in who created the best game. The #1 game this year was Frets On Fire and it's pretty awesome.

It's basically a simple Guitar Hero clone except instead of a special guitar controller you just you hold your keyboard like this

You hold the function keys while you *strum* the enter key.

The best part is the trash talking tutorial.

Give it a try, it's pretty fun. The music is pretty decent and you can even create your own songs if you want. Better get it before someone demands they take it down.
