Take a look at what we can do with light beams. To no surprise, a hologram helps a scene with R2D2, Luke, C3PO, and Princess Leia become one of the most memorable scenes in Star Wars history.



Tupac (as a Hologram) with Snoop Dogg, and Dr. Dre in concert. Light bouncing off of glass makes the image seem real. (Please pardon the unedited version shown here.) After the episode, we learned that 2 Pac was actually a two-dimensional project image (referenced here).


Upper Deck Baseball cards were really popular in the 90s with celebrities such as Michael Jordan and Wayne Gretzky, and Darryl Strawberry. During this decade, the trend was to an a holographic feature to the card to appear as if the image was three-dimensional if you tilted the card toward the left or right.

Pepper’s Ghost is an effect to create an illusion mainly in theme parks and Bouncing glass off of light doesn’t always mean three-dimensional (or a true holographic image). But, it’s still pretty neat that such a technique is used to display life-like images to audiences.

The Holodeck is used in Star Trek to create a large-scale holographic (virtual-reality) environments. On the  Enterprise, this technology was used extensively – so much so where, by normal standards, the attempts to personify relationships with artificial “beings” would be considered quite unhealthy. Here you’ll see the environment before human interaction or input.

You may even say that the Holodeck can make, well, anything possible.
