It’s the original Captain Kirk and Mr. Spock, William Shatner and Leonard Nimoy.  This caricature is from 2008 I think.  I found this great photo of a really young Shatner and a really young Nimoy:

I love the super old phaser in this photo.  Also, I just found out that “Phaser,” isn’t a word in Google’s dictionary.  Surprising!  Guess they don’t have that many nerds on staff.

The light in the photo wasn’t that exciting, so I made up my own.
