Very cool. It's interesting to note that Elevator Dispatch Algorithms are very similar to harddisk read/write algorithms. Hard drives have to accept read ("pick up") and write ("drop off") requests at different disk addresses ("floors") and figure out the most efficient way to handle all of the requests. In this analogy, traditional hard disks are simply very, very tall buildings wrapped around a cylinder.
