I came up with this idea when I was setting up my new computer. I have two computers, and I wanted to run the audio into one set of speakers. My first thought was to just buy a simple 2 female to 1 female 'Y' connector, but that apparently can cause problems if both sources are playing at the same time. Then the idea for a switch came to mind, but what to put it in? LEGOS!
