Transparent Aluminum

Technically, the Wikipedia article is called Aluminium oxynitride. Please don't tell the mod. This title (Transparent Aluminum) is more informative and also works as a Star Trek reference, which isn't a bad thing.

Worth noting that the material is not conductive or otherwise metallic in any way. In a lot of ways this material is similar to Alumina (Sapphire) which you could also describe as "Transparent Aluminum".

Conductive transparent materials do exist (see ITO https://en.wikipedia.org/wiki/Indium_tin_oxide), but this is not it.

Since everyone is now thinking of Star Trek IV:

The computer that Scotty uses in the Plexicorp scene appears to be a Macintosh Plus, but its internals were completely changed for filming. Its screen was replaced with one from an IBM PC to make it easier to synchronize its video refresh rate with the film camera's frame rate, and the "transparent aluminum" animation was created on an IBM PC by computer graphics company Video Image.

At one hour and one minute into the film, when Dr. McCoy hands Scotty the computer's mouse, is one of the few times James Doohan's missing right middle finger is visible in the entire franchise. The finger was shot off during the invasion of Juno Beach on D-Day.

The computer that Scotty uses to show transparent aluminum was originally going to be an Amiga, but Commodore would only give permission if they bought their own. Apple Computer was willing to give them a Mac for free.

Not sure I would qualify ITO as transparent. The thicker the coating the less transmission (but lower resistance) you get.
