Even before the iPhone, NTT DoCoMo was making phones with accelerometers that let you play chokkan (motion) games, send an email with a flick of your wrist, and use the phone physically to interact with applications. Recently, much has been made of using the onboard cameras to accomplish the same thing, and there are more and more cool applications coming out.
For those of us without Guitar Hero we can now use our mobile phones to play Chokkan Band courtesy of Taito.

The sensor on the phone detects movement, allowing anyone to use the phone as a guitar, violin, drums, or other instrument. Synched up together, you can create an entire band in perfect harmony, jamming out to songs downloaded through the service. The game is free, but songs come at a small fee.

Below is a video from the new online campaign for Chokkan Band starring their new…err…spokesmodel rocking out around Tokyo in public baths, at the laundry, in Shibuya. You know, normal places where you would play in a rock band with your mobile phone.
