Self Playing Strumming Circle Guitar
Auto-strumming guitars may not be on the cutting edge of technology, but the Circle Guitar by Anthony Dickens puts a unique twist on the idea. Put simply, it has an integrated mechanical step sequencer that rotates up to 250bpm beneath the strings to generate sounds, textures and rhythms that would be impossible with a normal electric guitar. By utilizing a mechanical device to strike the strings instead of a human hand, you can exceed what is physically possible and push guitar playing into a whole new level.

One gamer decided to up play Minecraft using only a real-life MIDI keyboard.

In Back to the Future, Marty McFly rocked a Gibson ES-345 electric guitar at the 1955 Enchantment Under the Sea high school dance, but this custom Time Machine bass by Doner Designs might have been more fitting. The Chicago-based father and son duo created this to pay tribute to the Michael J. Fox movie franchise, especially the time-traveling DeLorean, complete with flashing lights, a selectable destination year display and a flux capacitor.
