Ever wished that you had the SIXAXIS's tilt technology wherever you went? Well, we're not about to tell you to lug your PS3 around town, but we do have an alternative which you can put into your Nintendo DS. And it's actually more of a three-axis instead of six.

In any case, for US$ 25 at sites like DSPassMe, you can get yourself the DS Motion Card, which, according to the product page:

Contains a 3-axis accelerometer and a single-axis gyroscope, and plugs into the DS card slot to enable full motion sensing on the DS and the DS lite. It is the first tri-axis accelerometer that can be used for homebrew DS development, and the first and only accelerometer/gyroscope combination available for handheld gaming.
