The lights are on
Minecraft creator Markus "Notch" Persson made a Mario game with procedurally generated levels way back in 2006. Now 18-year-old Robert Kleffner has ported the Java game to a more flexible HTML5 platform.
Infinite Mario is playable in HTML5 right here if you'd like to burn away your lunch break. Be warned that you play on your keyboard and that it was a little sluggish on my computer. But it's kind of neat for five minutes or so.
If you've tried it out, what do you think?
