I am also trying to find the creators and learn more about sticker making. There are some artist collectives and artspaces in town. I think I found this sticker in the Clinton Street neighborhood of Portland.

Also one of my favorites. I think it probably comes from a tormented software engineer who also does street art. I like how people say they dream in other languages, but I never have heard of a php or HTML dreamscape. Maybe. But looks like this cat doesn’t find the machine liberating.
