If you haven't played Valve's Portal yet (and really, why haven't you?) then you may not comprehend the sheer fantasticalness of this video clip created by 256byteram of Commodore 64 sound hardware performing the game's closing theme, "Still Alive" . 

Bah. I liked the terminal theme from Portal so I made it real!

Everything on the terminals and sound is controlled by an Intel 8080 Microprocessor at 2MHz. The sound chip is a MOS SID (From a Commodore 64).

Original MP4, a preliminary MP3 and the assembler source code is at http://files.1338.info/portal/

As someone who had a Commodore 64 as a child, this composition really hits the sweet spot for me.  Why would someone go to the trouble of coaxing ancient hardware to output the theme from a modern video game?  As they say at Aperture Science, we do what we must because we can.
