Hitachi has created a humorous animation that explains in easy to understand terms, with music and dancing of course, how their new technology is going to allow for an exponential increase in the size of storage media - http://www.hitachigst.com/hdd/research/recording_head/pr/PerpendicularAnimation.html

Watch this and tell me what you think.  My initial reaction is longing for other high-technology firms to follow suit and explain in layman's terms what they do.  I know it would definitely make me smarter and would probably help me when it comes to picking stocks too :-)
