Images that represent word "programmer"

[ZipTie3182]

I'm making a shirt for a mentor as a joke and need images that would create the word programmer. This is a bad example, but the first thing I thought of was putting a "pro athlete" next to something that makes you think of grammar, so when you look at the images you think, pro and then grammar, and then combine them to make programmer.

Can anyone think of any creative images to use? Preferably I would like them to be simple enough to be made in one color since I'm cutting vinyl to make the t shirt. I'm hoping CD can come through on this

Happy Build Season,
