In the fun category, Professor Eric Faden of Bucknell University has created a video review of copyright principles.
You're probably thinking, "How could anyone make a video about a legal concept even mildly entertaining?" But Faden's truly inspired video works on many levels because it consists entirely of extremely short clips (often no more than one word) from a wide variety of animated Disney movies.
It's thanks in large part to Disney that copyright - which was designed to encourage creativity by giving the creator control over copying for a limited time - now lasts for the life of the creator plus 75 years, or, for a work of corporate authorship, 95 years.
But thanks to the short length of the clips, its non-profit educational nature, and the fact that it would in no way affect the potential market for the copyrighted works, Faden's video undoubtedly falls under fair use.
