I don't think that reddit thread is the original source. Someone in the thread links to a larger-sized image which appears to be from https://funnyjunk.com/Cognitohazard/pxMTMck/.

EDIT: here's an even earlier source, from over a week ago (note: thread contains other strange but mostly safe for work images) http://boards.4channel.org/x/thread/22512161/cursed-image-th.... 512x512 seems like a more likely size for the image to have been generated at, at least.

EDIT 2: here's yet an earlier source, from March 10: https://www.instagram.com/p/Bu2IkGylneb/. Someone in the Twitter thread mentioned this as being the original source.
