Can you explain the desire? Is it just nostalgia? I just don't understand the need for a screensaver for a VR device. Do people idle long enough with the VR device worn for a screensaver to come on?
In addition to their functional purposes, screensavers are aesthetically pleasing, and experiencing them in 360° immersion for short periods of time is something some people would enjoy. Perhaps there's a novelty factor here, i.e. a desire to experience familiar things in a new context, but I don't see where nostalgia would apply, other than to the flying toasters imagery specifically.
