List views are so 2007; next up in the growing line-up of visualization interfaces is a new service from Youtube that lets you visually search related videos.

Looking perhaps a little too much like (and moving noticeably slower than) digg labs' swarm, related videos move around your current choice in multi-coloured bubbles. As you scroll into the other topics, the recs shift based on your preferences and the bubble colours change to help you keep track of which themes you've chosen and those you've steered away from. Click on any bubble to watch the vid. A white line, giving you a nifty trail of breadcrumbs to find your way back to where you started, instantly connects the videos you decide to watch.

Currently only available in full-screen mode and not yet on all videos, the search takes a little bit of time to get used to. Once you're in the groove and let your right brain take charge, it's easy and fast to intuitively move around and find a whole treasure trove of videos you probably wouldn't come across by search alone.
