Quite possibly the coolest and most perplexing musical device I have come across on the internet is the Chukka Kinetic Music Player. Powered by the movement of your hand this device gets its inspiration from worry beads that you twirl around your fingers as a sort of therapy.
Thomas Mascall is the brilliant mind behind the Chukka Kinetic Music Player and quite the artist I must say too as each set is beautifully patterned. To have an MP3 player with an unlimited source of power is probably the greatest thing to ever be conceived, yes even better than sliced bread.
