It was very hot in LA one day.
I was asked during my time at Facebook to help design a tshirt for their machine learning team. While this wasn't the design they went with, I decided to still draw a bunch of machines learning human things. An engineer later commented, "it's nice that we're representing machine learning closer to where it really is, in its infancy."
Machines learn to: read, exercise, jump rope
In my first week at Facebook, I learned our payments team mascot was a bunny — so I designed characters for button pins that mixed and matched for C2C, C2B, B2C, and B2B teams.
(The B stands for bunnies, of course.)
