Artist Miriam Carothers is showing her series of string theorist portraits in NYC this month. Above is Alexander Polyakov. You can see intricately written equations transformed into the author at gallery SENSEI from June 6th to 18th.
From Miriam's press release:
Each portrait is frenetically colored with the cryptic, codifying writings of formulae and mathematic equation, discreetly laying out the foundations of the universe. These writings were supplied by the physicists themselves, and by delegating this act to the subjects of the work rather than the artist, we see not only the existence of the universe in these equations, but the existence of the physicist.
