It's called Ocean Scenes. Well, it's not really a game so much as a gadget.. basically it's an ambient experience I've created, that makes your TV look like you're looking out a window onto some nice beach scenes, complete with moving waves, customizable scenery and different sound options. Great to have on when you have friends over for a few drinks or you're sitting around playing Risk or something. Also wonderful when you have a *ahem* ladyfriend over... ;)
If you have an xbox, go ahead and queue up the trial version for download on this page, or if you feel like supporting a fellow Newgrounder and have 200 MS points floating around, you could always grab the full version ;)
You can also grab the game straight from your Xbox 360 console in the marketplace, of course. You'll find it under Game Marketplace>Community Games>New Arrivals.
I've got a full-on game in the works (see my previous news post), so keep your eyes open and your MS points loaded ;)
