Usually when I come across some of my artwork used elsewhere/improperly, or without permission, I pursue the infringer for their cheek, and in some circumstances, seek renumeration for an unauthorised usage (FAQ on this subject coming soon!).

However, in this instance I was amused, and take it as a sort of compliment that my rendering of an Atlantis Stargate was used for this humorous meme. 🙂

I suspect the image was acquired here: http://stargate.wikia.com
