Linkage dump:
Easy homopolar motors.
A brilliant mashup of Sir Mix-a-lot and Mr. Astley.
Flute beatboxing! Some Star Wars art-mashup contest. Most of them are average/mediocre, but there's a few creative ones I quite enjoyed.
Set phasers to ROCK! A throwaway joke that is far funnier than it has any right being.
The Matrix vs. Carl Sagan. Morpheus's expressions are priceless.
