Nothing so new about this!

In the early 80's there was equipment which involved wearing goggles and headphones and having a private light-show.

It was possible to programme in many different ways.

Some programmes were purely "psychedelic entrtainment" others were dedicated to dealing with "problems".

A lot of fun they were too but for some reason they never made it big in the marketplace.

Sensory deprivation tanks also lent themselves to similar therapeutic uses. Also lots of fun for anyone who didn't suffer from claustrophobia. It was a bit of a nuisance haveing to wash the salt off afterwards.

A pioneer in this work was John C. Lilly who also worked with dolphins.[Not to be confused with another John Lilly.]
