If the idea of an iPad Band floats your boat, you will love the adorkable Ge Wang. He has a wonderful Ted Talk on how he creates computer generated music and The Orchestra of the Future. Ge also formed the Stanford Laptop Orchestra and the Stanford Mobile Orchestra. Mr Wang took his creations and turned them into fantastic iPad Apps under his company name Smule. Check out Smule. Not only do you get the instruments, you get a community with which to jam.
