As we were critiquing all the student animations turned in for my ART 210 Graphic Design I final, one piece prominently displayed the Photoshop twirl filter.

I commented to the class that when I see that filter, I recall how it was used by an infamous pedophile to hide his identity online, but international police managed to reverse it enough to allow for identification which then led to his capture.

My students were like, “huh,” and then we moved on with the critique.
