Who needs a big expensive piano, really? After all, you can make beautiful music for only a few measley bucks! Just “pry open a Gameboy, tinker with its electronic guts, plug the re-engineered result into a Speak & Spell, duct tape it all together, sprinkle liberally with glitter, hook it up to an amplifier and let the good times roll.” The act of creating such self-hacked instruments is known as “circuit bending,” and a new festival celebrating the fad may be proof that it’s becoming a legitimate form of artistic expression.
