Some people are just too clever for their own good. Take Reddit user "golgobot" and his synthesiser built from sounds chips taken from three Commodore 64s. Combined and programmed to work in concert, they can produce some fairly awesome-sounding music, like the Game of Thrones theme in the video.
The chips themselves are SID 6581s, made by MOS Technology. The hardware was used in several models of the Commodore, including the 64 and 128.
I'm not sure if it's the old school tech, the flashing LEDs or just the music, but as soon as that franken-device started belting out that now-familiar tune, I couldn't help but be impressed.
