Sammelraum can only be roughly translated to "space where we collect (what?) or gather (why?)" or probably also "space where we are collected (by whom?)"

A paradoxical example of recursive self-reference: the label Sammelraum is assigned to both the creator of a visionary virtual space - the Sammelraum - and at the same time denoting this space itself.

"Sammelraum expresses his visions about the future and and destiny of mankind [...] in his images, projecting the universe onto a perfectly highlighted egg." © El(k)ement
