musicFromMotion:  mFM converts your slick grooves into sweet tunes.  Body movements are transmitted wirelessly to a host computer and then translated into pre-programmed beats and instruments.  And everything is reconfigurable on the fly; you can serenade or offend the airwaves however you please.
nRF24L01+ Raspberry Pi adapter:  elegantly connect the powerful, ubiquitous, and cheap nRF24L01+ to the [same adjectives] Raspberry Pi.  Don’t hassle with hookup wire or protoboards anymore — with a few common parts and a few bucks this adapter will solve all of life’s problems (at least the nRF24L01+ and Raspberry Pi-related ones).
musicFromMotion Rx: Several times a day I’m asked, ‘Hey Calvin, I really dig your nRF24L01+ adapter, but it’s so bulky! And I have all these mini nRF24L01+ modules lying around with no way to hook them up to my Raspberry Pi! Will you help?’ Behold: a sleek, slick, slim solution that’s barely larger than a postage stamp and cheerily dwells within your RPi case. Originally made as an upgraded receiver for musicFromMotion, this cool puppy can be used anytime you need an nRF24L01+ transceiving fix.
