Notch trying jsFiddle
Tooting my own horn here, but here's my own little "Minecraft" renderer in Neja, circa 2005 ( <a href="http://www.youtube.com/watch?feature=player_detailpage&v=0JB66fttJXY#t=143s" rel="nofollow">http://www.youtube.com/watch?feature=player_detailpage&v...</a> ). Over 4 years before Minecraft, and even then that was nothing new. It was kinda cool for JavaScript, in 2005, but all things considered, it was pretty lame compared to Ken Silverman's voxlap for instance.<p>The "cool" thing about this demo, was that Canvas was not widespread back then so I generated all the chunky effects on the fly as 24bits BMP image, then made a data: URI and update an IMG tag.
