Having a spare room is cool, being able to create a room dedicated to the Portal game series would be just so special and that is exactly what we have here. This room has been converted into a sort of mini Aperture Science lab where as we know everything seems to go wrong time after time. However, do not mention that to GLaDOS!
According to the creator of the Portal room;
Although the foundation of my childhood was largely based around the Mario Brothers / NES era of gaming, I just wasn’t sold on the idea of having a room based around it. It took me a little while, but I finally decided on doing up a theme based on the game Portal / Portal 2. Now I’m not claiming too be the first one to do this (While Googling for ideas I found about 2 or 3 others), but by adding my own touches I would create a room which ill enjoy spending some time in.
