One word, WOW!
This have to be the most insane skills ever. Apparently, there's this guy called Isotksh that plays Super Mario World to music, using the game's build-in sound to match the beats. When the music starts mashing up tempo, the gameplay does the same. This is 11 minutes of Korean insanity, ONLY THEY COULD GET THIS RIGHT!
After you've checked the video and realized that it's now a global fact that we all suck in Super Mario World, you can go comfort yourself with the updates above.
A whole bunch of updates, just because we lack to update daily. I'll try to get back to a daily update here. 
Sorry, I was the weekend in Belgium, without any internet

Check the updates before you go to work
