Check out this interesting post on Kotaku today.
In Japan, Nintendo is launching a serviced called the Wii Room, which will deliver original animated cartoons to Wii users. The toons will consist of Miis - the bubble-headed Wii characters - and it sounds like you may be able to cast your own Mii into the action (if that's not the plan, it should be).
Brian Ashcraft points out that - given the fact that Nintendo asks for, among other things, your blood type and buying preferences - it sounds like a thinly veiled market research machine. Maybe. But it's interesting to see a company like Nintendo venture into it's own machinima - game-powered toons, which I've written about in the past for Spectrum.
