My Visualisation of the Portal Problem

Speedy Thing goes in, Speedy Thing Comes Out

Not made for mobile

To me, in order to understand the portal problem we should imagine portals as doorways, i know that a doorway cannot have two sides in differing places but that's ok if they lead to ""different"" rooms. this shows how when following this train of logic, the momentum that flings the cube comes from the other room ""moving"" (due to perspective of the main room). I know this problem has been done to death but i wanted to visualize it
