What MK likes to do is edit videos. He would happily spend 16 hours a day huddled before the computer watching and producing YouTube Poop. He chops up scenes from his favorite cartoons and from games, and rearranges them to make something new. Most of it is extremely repetitive (big surprise there) and sometimes hard for me to fully appreciate (apparently not so for his peers, as the videos he has made have had 75,000 views on YouTube in the past six months). He did one yesterday that I particularly like. I think it's the kind of 80s technopop sound that make it accessible to me. It is, it seems, a riff on another video montage to the same music, but I like MK's version better than the original.
By the way, you definitely want the sound on for this one, but the volume is set a little high, so if you are at work, you may want to have your hand on the volume control.
