Enjoy your sensual overload!
Jeff Minter has been designing video games since the early days of the medium. And since the very beginning an air of anarchy and trippyness has been a constant in his creations. Since Tempest 2000 he has been refining what I’d like to call the psychedelic “space” shooter (look here for Space Giraffe).
But he has released a game/ “light synthesizer” that is actually called Psychedelia as early as 1984.
Check out the man’s work! You won’t be disappointed.
