I want to write an image display program that's really slow. But while you watch it draw the pixels from line to line you can be comforted by the knowledge that the computer is working really hard. On other stuff. Like, just before pixel 422 it read (parsed) the complete works of shakespeare. after Pixel 97677 was drawn it pinged the last twelve IP addresses that came to that server. And just before drawing pixel 77321 it Created a text file just a LITTLE smaller than the available size on the disk, filled it with the word "poop" and then deleted it.
