Editing Pulfrich effect (section)

===Examples===

The effect achieved a small degree of popularity in television in the late 1980s and 1990s. On Sunday, January 22, 1989 the [[Super Bowl XXIII halftime show]] and a specially produced commercial for ''[[Diet Coke]]'' were telecast using this effect. In the commercial, objects moving in one direction appeared to be nearer to the viewer (actually in front of the television screen) and when moving in the other direction, appeared to be farther from the viewer (behind the television screen). Forty million pairs of paper-framed 3D viewing "glasses" were distributed by Coca-Cola USA for the event (though they were originally produced and intended for a May 1988 3D episode of ''[[Moonlighting (TV series)|Moonlighting]]'' that never finished production due to a writer's strike).<ref>{{Cite web|url=http://www.davidandmaddie.com/3d.htm|title=The Lost 3-D Moonlighting episode}}</ref> The right eye's filter was grayed purple (resembling red wine color), while the left was very light amber (resembling white wine color). These colors complemented each other to produce the Pulfrich effect while avoiding distortion in the broadcast's natural colors. The commercial was in this case restricted to objects (such as [[refrigeration|refrigerator]]s and [[skateboarder]]s) moving down a steep hill from left to right across the screen, a directional dependency determined by which eye was covered by the darker filter. The commercial was said to be created using Nuoptix 3D technology to create the Pulfrich effect.

The effect was also used well throughout the whole 1993 ''[[Doctor Who]]'' charity special ''[[Dimensions in Time]]'' and in dream sequences of the 1997 ''[[3rd Rock from the Sun]]'' two-part season 2 finale ''Nightmare on Dick Street''. In many countries in [[Europe]], a series of short 3D films, produced in the [[Netherlands]], were shown on television. Glasses were sold at a chain of [[petrol stations]]. These short films were mainly [[Travel literature|travelogue]]s of Dutch localities. A ''[[Power Rangers Lightspeed Rescue]]'' movie called ''Power Rangers in 3D: Triple Force'' (later broadcast as two-part ''Trakeena's Revenge'')<ref>{{Cite web|url=https://www.imdb.com/title/tt0246868/|title = Power Rangers in 3D: Triple Force|website = [[IMDb]]|date = 3 July 2000}}</ref> sold on VHS through [[McDonald's]] purportedly used "Circlescan 4D" technology, which is based on the Pulfrich effect, but there was very little 3D present. In the United States and Canada, six million 3D Pulfrich glasses were distributed to viewers for an episode of [[Discovery Channel]]'s [[Shark Week]] in 2000.<ref>{{Cite web|url=http://www.3dglassesonline.com/press-release/3D-television-event/|title = TV Event 3-D Glasses}}</ref> Animated programs that employed the Pulfrich effect in specific segments of its programs include ''[[Yo Yogi!]]'', ''[[The Bots Master]]'', and ''[[Space Strikers]]''; they typically achieved the effect through the use of constantly moving background and foreground layers.

In France, "Le Magazine de la Santé", a long-lasting popular medicine TV-show, has extensively presented the effect in October 2016, inviting its viewers "to see the program in 3D for the first time".<ref>{{Cite web|url=http://www.allodocteurs.fr/insolite/le-magazine-de-la-sante-en-relief-avec-de-banales-lunettes-de-soleil_20554.html|title = Le Magazine de la santé en relief (Avec de banales lunettes de soleil !)|date = 14 October 2016}}</ref>

Some episodes of the Italian/German TV game show "[[Tutti Frutti (1990 TV series)|Tutti Frutti]]" utilised the effect. One of the showgirls stripped topless while others danced around her in an anticlockwise pattern, while two additional rear layers were created by graphics moving at different speeds. It is not known how viewing glasses were distributed. Episodes are widely available on the internet, but only a few use the Pulfrich effect.

The video game ''Orb-3D'' for the [[Nintendo Entertainment System]] used the effect (by having the player's ship always moving) and came packed with a pair of glasses. So did ''[[Jim Power: The Lost Dimension in 3-D]]'' for the [[Super Nintendo Entertainment System|Super NES]], using constantly scrolling backgrounds to cause the effect.
