Duchamp’s “Étant donnés,” composed of a naked lady collapsed against a lurid natural palette (the gas lamp she holds proves (perhaps) she is not a corpse), combines the technology of the peepshow with the lush colors of the panorama and functions as a striking VR precursor.  

Interesting to see that simulations of natural landscapes are still happening with vr tech. (Simon Robertson’s “Dream Realm 1” (2014)).
