The monster Gigabyte returns! At least that's what Hacker has planned. The bad guys bring the wrecked robot deep into a tropical jungle for the one day of the year when the position of the cybersun atop a Mayan-style pyramid can bring Gigabyte back to full power. Jackie, Matt, Inez and Digit must work their way past giant snakes, spiders and other creepy critters in order to block the cybersun before it can energize the metal monster. There's only one way to get it done - they must master the secrets of tessellation.

This activity introduces the player to reflections and angles through experimentation with a kaleidoscope. By moving the mouse through the kaleidoscope, the player can observe the reflections in 4 squares which have been divided into 8 triangular mirrored panels.
