Not exactly original to make a lego portal moc, but I did it anyway; (or at least, when I made it when Dimensions first came out, I never got round to taking a photo then).
This 'photo' is actually a blend of two different photos I took with different depth of fields to try and give the illusion of there being no DOF. A couple of spots are a bit blurry but I think I did alright.
A couple of extra pics of the little extras here:
Edit: wow this ended up on Kotaku
