Manipeo is by far not the only site for videos! I recommend the following video sites:
Juggling.tv – hosting nearly 10000 juggling videos!
ClownTube.tv – One of the inspirations for this site, a great database for clown and circus videos
MinistryOfManipulation.com – Another inspiration for this site. It has not been updated for a long time but you can still scroll back through great videos
EloiPrieur.com – A French film maker with some amazing videos for free download which you can’t find elsewhere on the web
