Sony Rolly

I came across this moving speaker system a while ago, but thought I'd share it as it's fantastic!



The speakers move, turn, roll, spin and flutter to the sound, beat, rhythm and pitch being played through them.
I think it's a great piece of technology and I'd love to see them on the market! Although they might need to be developed so they wouldn't roll off the end of a table!

Edit: ... according to Wikipedia, the Rolly was released in 2007, but was discontinued soon after :(
