Found it! It's actually called MyoWare: http://shop.openbci.com/collections/frontpage/products/myoware-muscle-sensor?variant=29472011267 http://shop.openbci.com/collections/frontpage/products/myowa... It's a little 3-lead EMG sensor intended for use with arduinos and the like. It's not quite as nice as the Myo (it uses sticky electrodes), but it's a similar form factor and much cheaper.
