A two-story-high model of a personal computer, simulated to be working interactively.

The purpose of the exhibit was to show the anatomy of a computer and to explain how the various parts work and communicate with each other.
Before entering the computer's chassis, visitors could roll a giant trackball to play "World Traveller" on the giant screen.
 Wall-sized graphics by David Macaulay and interactive exhibits explained how all kinds of information, from text, graphics, video, music, as well as computer programs can be represented as 1's and 0's.
Inside the giant chassis, visitors walked between a wall-sized graphics card and memory card to the microprocessor, upon which a projected electron microscope imagery of a CPU's circuits in operation appeared.
 Further on, a RAM set of modules plugged into the motherboard included reveals showing electron microsope imagery of memory circuits,  Peering into a mini-van sized hard drive, visitors could see read/write heads position themselves on either side of rotating platters.
Richard Fowler was recruited from The Science Museum, London/Bradford, as exhibit designer.
 The exhibit garnered international publicity and more than doubled visitor traffic to the museum.
