Primal Screen: Designer of the Sprout logo

I did a little research on the Sprout logo.

Turns out it was designed by Primal Screen, who also did idents for Cartoon Network, PBS Kids/PBS Kids GO!, and of course, PBS Kids Sprout.

Self-described as: 

A multi-platform design agency, Primal Screen distills a keen knowledge of brand essence and serves it to every screen. Mmmm...tasty.

It's quite/kinda interesting to find out, as it is an outstanding logo!
