This game works with: SheepShaver, Basilisk II,

Our eyes have to resort to incredibly sophisticated trickery to accomplish their task. As is pointed out in the introductory section, the retina of the eye--onto which the images we "see" are projected--is a two dimensional surface. The brain has to take these images from each eye and blend them in a way that will produce a perception of the world that has space and depth, as well as color and motion.

The aim of this handsomely designed CD-ROM is to explain the mechanics of this phenomenon, as well as the fascinating optical illusions our eyes can play upon us. "Illusions lead us astray," says hostess Norma Lana, "by the same mechanisms that help us see correctly."

The disc has been designed as a Benham disc, which you can spin to see coloured sectors and ring shapes,
originated from that black & white ones printed on disc.

The 2nd download is the English version, by Byron Preiss dated 1997, and licensed to Marshall Media 1998

Architecture: 68k PPC x86 (Windows)

This is a hybrid CD-ROM for PC & Mac.

System requirements Mac:
68040 @ 25 MHz, Mac OS 7.1+

System requirements PC:
Pentium @ 133 MHz, Windows 95/98, sound card 16-bit.
Requires QuickTime 2 (32-bit version) installed in your System
(if not installed yet, it'll be installed automatically).

Common requirements:
16 MB RAM, screen resolution of 800 x 600 with 16-bit color depth, 4x CD-ROM drive.

Althought box tells a minimum system requirement of Windows 95/98 on the PC partition, this CD includes an application for Windows 3.1, too. So probably this will work with this operating system, too.

The German version installs the game into the folder "Navigo" on your Macintosh Desktop.
