In the SCP universe, there are communities besides the containment Foundation who deal with "anamolous" (supernatural) objects and phenomena. One such group are the An-Artists. (anamolous artists) Stories about them usually have them creating artwork that otherworldly/supernatural/"anamolous" in some way. Like maybe pictures that you can enter and have worlds in them. Or pictures that act as teleporters into space... or houses made of weird geometry that require someone capable of walking on the walls.
There have been many such tales and SCPs on the site over the years, the most notable of which is a group called "Are We Cool Yet?", but this was just supposed to be a generic an-Artist, not someone in particular.
I may have drawn a little bit of inspiration from
