Moff bills itself as a “wearable smart toy”. Grab a broom and strum, and the Moff bracelet will emit a guitar sound. Grab a banana and point it like a gun, and your shots ring out. A pretend tennis racket, you’ll hear a swat sound when you swing.

I’m not sure this is useful as much as playful, but I love the concept and I think there’s something to this. I’m interested in watching this evolve.
