Apple commisioned Tom Lichty and Tom Crosely to produce a sales demo for the then brand-new Apple IIGS that would showcase it's capabilities in its own unique way.
The demo comes on two disks and can be run from a single drive system or with two 3.5" floppy drives attached. The program will boot and then stop loading at a black screen. At that point, if you have a single disk drive, you'll need to eject the first disk, replace it with the second disk and hit return to continue.
There are some instructions on how the program can be installed to a larger ProDOS volume included in the zip archive.
