The Trout Mask Replica System is a sophisticated hardware/software combination that allows the user to view the world through the eyes of a fish in a stream.

• The HMD provides a stereo, wide-angle, bi-directional monocular view (known as the "trout window"), with full-jaw force feedback and vibrational feedback.

• Companion software provides a complete stream simulation, including the fishermen on the bank.

• System allows for fun games like "Steal The Expensive Lure", "Drop Off The Line", and "Catch The Caddis Fly". We have even created our own "Become Mr. Limpid" world.

• Software simulates complicated fluid dynamics like surface ripples, rapids, variable-depth refraction and eddy currents.
