A chainless chainsaw is just a dull piece of metal sticking out of an engine. So I think your assumptions are correct.

There is also a chest strap that has been invented to let deaf people "feel" the bass in heavy dropped electronic music. I highly recommend it. Even though i can hear perfectly normal, it blows me away how awesome it is. And i feel like programs could be written so you could "feel" live music that hasn't been written down yet. I'd love to know what you think about that.

Someone beat me to it, but it's called the SubPac and i think you could find some great uses for it.
