The upper case theta was in 1969 made into an Ecology Symbol by cartoonist Ron Cobb, that later became associated with Earth Day.
Ron Cobb created an ecology symbol which he published on November 7, 1969, in the Los Angeles Free Press and then placed it in the public domain.
During the early '90s, Ron worked with Rocket Science Games. His designs can be seen most notably in Loadstar: The Legend of Tully Bodine (1994) and The Space Bar (1997), in which he designed all the characters.

Cobb's editorial/political cartoons were a celebrated feature of the Freep, and appeared regularly throughout member newspapers of the Underground Press Syndicate.
•
Among other projects, Cobb designed the cover for Jefferson Airplane's 1967 album, After Bathing at Baxter's.
Syd Mead and Ron Cobb both designed numerous versions of the UD4L, but James Cameron ultimately built his own miniature out of AH-64 Apache helicopter model parts.
