>It's 3D all over again.

As a side note, people tend to dismiss stereoscopic 3D as an example of a recent gimmick - and yet this is the technology that has had its largest peak in the 1800's, and has been consistently gaining grounds and advances since.

It has been coming and going in waves, but it has persisted for over a century, and has never been abandoned by enthusiasts - such as the astrophysicist Brian May (widely known for his other work), who has documented the life of a musical collective he has been a part of in 3D[1], and continues the push for adoption and appreciation of 3D tech[2].

Resilience of 3D at home is something tech like Alexa can only hope for.

First time I hear about Brian May being an astrophysicist. Very surprising (to me at least). He was awarded his PhD in 2007, for his study on the formation of zodiacal dust clouds.

Until 2007, Brian May was just another PhD dropout.

...if you forget him being the guitarist of Queen who also wrote about half of their songs.


I think there was a radiology journal dedicated to stereoscopic X-rays 100 years ago.


I am not talking about scientific applications.

I am talking about tens of millions of sterescopic photographs and viewing devices[1] made in the late 1800's, with stereoscopes being about as prevalent and accessible as radio sets and TV's before the transistor era.

You can still buy a 3D card more than a century old for under $5 in vintage stores around the US.

And yes, you can slide your cell phone into a stereoscope and enjoy your 3D/VR apps 1880-style. (Today's VR headsets for cellphones are just 1800-s stereoscopes with a rubber band).
