Voice-controlled toy piano

We know that you can teach dogs tricks, even though they’re old ones, but to have an inanimate object listen to your every command and do your bidding? No, you don’t have to descend from Mt. Olympus to obtain such “powers”, as Ranjit Bhatnagar demonstrated with his voice-controlled toy piano. This could really creep some people out, as whenever they make some noise it will play, but when all returns to a deathly silence, the piano will automatically remain as still as a leaf.
