So, now that I've finally got Rock Band ...

I get this link this morning:

In short, it's a belt buckle that has a 'virtual' pick that when you strum over it, it plays a bit of music. Like you're playing guitar. And it's being shipped in March.

I think I want this. Just to annoy the crazies on the Skytrain.
