Few people have heard of it, yet many consider John Blankenbaker's KENBAK-1 to be the first commercial personal computer.

Koss introduced these headphones over 40 years ago, and they remain affordable favorites to this day.

Red Raven Animated Records

Animated

When portable CD players were relatively new, a friend of mine had a unit with a little window in the lid.  I thought that it would be really cool to create a CD that had sequential frames on it that would seem to animate through the window.  There are a number of technical reasons why that wouldn't work (the window doesn't have a shutter, every CD player has a different window, etc.), but it still seemed like a good idea.

Nice video from Kempa.com of the Red Raven in action
