So I was reading Ars Technica's article on perpendicular storage... Perpendicular storage is a pretty neat way of increasing the storage capacity of hard drives by writing bits up and down instead of side to side, giving a density increase of between 30 and 400(!) percent. (Non-techies: Up to 5x times the songs on your iPod.) Apparently Seagate is starting to introduce this tech in actual products. (Read the Ars article for details.)
However, one of the links Ars gave is one of the weirdest introductions to a new technology. It's a cross between an explanation and Schoolhouse Rock. Warning: flash animation and music.
