During the weekend I stumbled across a site that is made of sheer awesomeness!
Screen shot of inbflat.net
http://inbflat.net/ is a collaborative music and spoken word project developed with contributions from the general public.
Twenty videos of music performed on various instruments including a banjo, piano, Kaoss Pad/synth, guitars, violin and many more can be played simultaneously and be mixed together using the individual volume sliders. The beauty of this is no matter when you stop and start any of the videos the combined sound always works. Magic! What a great idea. Try it here and see for yourself.
