The longer you watch them, the better they get.
Featuring remixed pop culture videos using techniques in culture jamming such as subtle satire, détournement, and subvertising among others. While somewhat difficult to initially perceive... these are quite simple (and fun) to execute.
Featuring single-source remixes as well as multi-source mashups put to a (hopefully) catchy beat. I find these easy to imagine... yet hard to successfully execute with style. I admire anyone who can do it :)
All videos dealing with time in some form.
