Take a bunch of lego, a camera, and a physicist with a PhD and a geeky sense of humour. Add the Web, and you have IWC. This is a multi-themed comic, I'd say how many themes there were, but more keep being added.
Warning - massive archives. Not entirely necessary to read them to get the jokes, but you'll probably end up doing so anyway. As of WikiNow (6th June 06) 1227 strips and counting. CopiousFreeTime recommended.
