This tech predates Valve's Portal, although I doubt it is the first attempt at this.

AFAIR it did; there was one point at which you emerged inside a semi-transparent container, at ~1/10 of your original size, and a full-sized alien was looking at you. > This tech predates Valve's Portal, although I doubt it is the first attempt at this. Portal was inspired by Narbacular Drop (2005). https://en.wikipedia.org/wiki/Narbacular_Drop https://en.wikipedia.org/wiki/Narbacular_Drop
