I went in with the idea of using some time to create a Lux map of Vancouver, since there wasn't one yet. It was a good scale project to do, since I was able to get it (mostly) done and also spend a bunch of time talking with the other nerds there.
I cleaned it up more after the event, and spiced up the theme with creative commons photos from kidcadaver and Jaako. It's now gone through the MapLAB and has been released to the plugin manager inside Lux. If any DevHousers want a copy, send me an email.
