The Quest for Visual Immersion
A Brief History...
30,000 B.C.E.
2001 A.D.
Visual Communication was used by
prehistoric humans over 30,0000 years ago as
evidenced by cave paintings Chauvet,
Verona and others...
These caves were immersive environments...
…Were they perhaps prehistoric “cathedrals”
designed to invoke a sense of awe?
Ancient Architects created Massive
Immersive Environments...
