You Chose This Path.
Finally got some photos done (thanks dad!) and as you can see it turned out preeetty gooood. the room was only supposed to be a backdrop and so that's why it's only kinda half accurate, also, yes *I know* that the head is the portal 2 version, but after tinkering with some other head designs I didn't think it was worth changing. Inspired by Catsy, Ben, Diegoboy.
EDIT: just to tell everyone, I have just made the "Lego Portal" group please add your portal-related lego :)
Don't worry, look at the next pic.
