While I was at DNA Ant Bully was being created in stereo for Imax. To
preview on the workstations they took the rendered pair, flipped the left
eye and composited them together side by side.

This was loaded into a flipbook and played such that it overlapped the
monitors. Left eye render on the left monitor (flipped horizontally) and the
right eye render on the right monitor.

A mirror ("first/front surfaced, 4-6 waves"... about the size of the
monitor) mounted on an adjustable stand was placed between the monitors so
that it reflected the left monitor. You put your nose towards the mirror,
the left eye looking at the reflection of the left monitor, the right eye
looking directly at the right monitor.

Very effective full colour 3d preview at your desktop.
