If you are a computer geek, this is for you---NICE graphic on super-computing...

From BBC: In graphics: Supercomputing superpowers (Click on this link for interactive graphic)

The biannual Top 500 supercomputer list has been released. Use this graphic to explore the world's fastest number crunchers or find out more about alternative supercomputer powers .
About this data:  The data used to generate the interactive treemap visualisation come from a draft of the June 2010 TOP500 Supercomputing list. This ranks most of the world's fastest supercomputers twice a year. There may be minor differences between this list and the final published list.
The graphic allows you to see the visualise the list by the speed of each machine; the operating systems used; what it is used for; the country where it is based; the maker of the silicon chips used to build the machine and the manufacturer of the super computer.
The maps were produced using the Prefuse Flare software, developed by the University of California Berkeley.
