check out the Guitar Hero III embeddable widget. The widget debuted on Wired’s Game Life blog, but anyone can grab the code and put it on their site or blog. Activision’s mini-game widget is not easy to play (even on the lowest level), but if you manage to hit the right notes, you could be eligible to win prizes from developer Rocket XL and Activision.

There is no guitar controller, so you’ll need pretty fast fingers, and your keyboard’s keypad to show off your mad GHIII skills. The three (lame) songs included are Cult of Personality” by Living Colour (easy), “School’s Out” by Alice Cooper (medium), and “Metal Heavy Lady” by Lions (hard), each representing a specific level of difficulty.

It was impossible for me to hit even one note on this game, but a look at the leaderboard tells me it is not impossible. Give the widgetized game a try, and tell me if you think this game is masterable or just a cruel marketing ploy of some kind.
