[edit] Comments

Note to editors: The 1989 Superbowl halftime show was broadcast in 3D using this technique. (I remember watching it.) According to http://www.davidandmaddie.com/3d.htm , Moonlighting was to be the first TV show that used this, but the writer's strike of 1988 killed their plans. Also according to the same site, the 1989 Superbowl (Actually, a halftime ad for Coke, although I remember the whole halftime show being 3D) was the first time ever this technique was used on TV. Also, this link http://groups.google.com/group/rec.arts.tv/tree/browse_frm/month/1989-01?_done=%2Fgroup%2Frec.arts.tv%2Fbrowse_frm%2Fmonth%2F1989-01%3F& shows a discussion of the show from January 1989, shortly after the superbowl.—The preceding unsigned comment was added by 70.64.68.223 (talk • contribs) 04:21, 3 June 2006 (UTC).

I definately remember watching the famous rose bowl parade in 3-d with this technique. sorry, I dont remember the year. -SF

[edit] stationary objects

I agree that non-moving objects cannot be percieved 3D but I use this effect by making the things rotate. This is a viable possibility and I think it should be noted in the article. —The preceding unsigned comment was added by Honnza (talk • contribs) 16:43, 24 January 2007 (UTC).

[edit] stationary objects

I would point out that if an object is rotating, it is no longer stationary. The object might not change position relative to a fixed reference (e.g., the edge of a monitor or other objects in the immediate area) but the object has motion. It is this point-for-point change in position of the object's image on the retina that produces the Pulfrich stereo-phenomenon.

Another interesting example of the Pulfrich Stereo-phenomenon can be observed with dynamic random noise (DRN), like 'snow' seen on a TV tuned to a blank channel. If you place a dark lens over one eye, say the left, what you will observe is a clockwise-swirling maelstrom. Placing the dark lens over the other eye will reverse its direction.
