HappyEdit is a proposed project to remake Vim using modern web technologies. The project was started by Per Thulin who previously worked at Flattr. Per is looking for $10,000 funding to develop the application, but already has an initial version which is demonstrated in the Indiegogo video.
In terms of a crowdsourced project, the perks aren't particularly exciting. The most interesting aspect of HappyEdit is Per's user interface ideas -- rather than slavishly duplicating Vim he's trying to do new things with the web-based GUI.
