Buncha cool stuff here, including some videos and music, on various geeky topics.


Regarding the "optical pulse" that goes faster than light, Greg Egan has a Java applet that provides a visual explanation of this phenomenon here.

Maybe it was user error, but I downloaded the sun screen saver and it made my computer very sluggish...and caused a bunch of very odd error messages.

Re-booting took care of most of the problems and removing it from my screen saver list took care of the rest.
