Pillow Castle Games from Pittsburgh, Pa has come up with a new puzzle game that messes with reality along the likes of my personal favorite, Portal.    The tech demo shown in the video above takes forced perspective to a new level by letting you manipulate the size of objects based on where they are.  According to the Carnegie Mellon students who created the demo, “The Museum of Simulation Technology” is our playground we’re using to wrangle our brains around using your perception as a weapon. Think of it as a “proof of concept”.  It’s a bit difficult to explain so be sure to watch for yourself.
