By far my weakest sport, I love swimming. Getting into the water and getting into that zone where theres nothing but you and the water.
While a good population of multisport athletes come from a swim background, I don't (and I'm not alone). So I've been searching the web for some (free) swim videos to help with developing an understanding and visualization of proper front crawl technique. The following include videos of Popov's stroke, Ian Thorpe and front-crawl swimming technique.
