"Mysterious medallions" popping up on Bay Area sidewalks

There's a Happy Mutant reality hacker on the loose in Berkeley, California... affixing "mysterious medallions" on the city's sidewalks.

Berkeleyside reports:

There is a person out there with a sly sense of humor, a way with words, a working knowledge of Berkeley history and a desire to impart pithy observations.

He or she or they has been going around town the past few months affixing round metal medallions with clever sayings to sidewalks around Central Berkeley...

No one seems to know the creator’s identity, even though the question has been posed on Facebook and Twitter and even on Tom Dalzell’s Quirky Berkeley website.

“These days, just everybodytout le monde – is talking about the mysterious medallions that are appearing in Berkeley’s sidewalks,” Dalzell wrote. “You read about them in Berkeleyside, you see them on Twitter, your hip friends are talking about them. “Plaque” might be a better word for what these are, but medallion gives us alliteration with mysterious.”
