SVG in Wiki
Danny's hacked together something I've been dreaming about for the past few months: SVG support in a Wiki. My current annoyance with Wikis is that you have to learn a crummy syntax (I've explored zero learning curve wikis in the past) and you can't incorporate visual elements without a huge amount of hassle. This neatly solves the problem by providing an SVG whiteboard. The screenshot looks très cool. Amazing work Danny.
