Okay, my idea is pretty rough at this point but here's what I got so far.
SCP-###(I'll decide the number later)
To be stored in a 10x10 perfectly symmetrical room, guarded by two blind guards, on a completely symmetrical stainless steel cube. Any staff member who accidently views SCP-### is to be immediatly taken aaway for psychological counseling until mental damage is either confirmed or shown non-existant. Any D-Class personal who view SCP-### are to be immedietly terminated
Description: Though not observable in any actual physical form SCP-### has the ability to "jump" into any object viewed for aesthetic purposes. Upon entering, said object becomes what is described as "uncomfortable looking". This is effect is caused by SCP-### exploiting any asymmetry in the object, making it just noticable enough to cause mental distress as the viewer attempt sto figure out what's wrong with the object. Prolonged viewing can cause mental distress significant enough to drive a viewer to suicide. SCP-### seems to feed off this mental distress, as it feeds on more and more distress it can take over larger and larger objects.
Like I said, it's pretty rough. I'd really appreciate any helpful ideas or thoughts. I basically got the idea whilst having a bit of an OCD issue, so I hope it reflects that.
