The Laser Beam Harp
The laser harp has been created by Stephen Hobley. By placing his hands over the lasers, breaking the beam between the source and the mirror above, he can create a rather funky sound.
It reminded me of that sound that the instrument/portal opener/can opener thingy made from the Masters of the Universe film with Dolph Lungren. Nope? Was i the only one that seen that film? Ah well.
