Hamburgerpanda is an Etsy favorite of mine. I haven't bought anything yet, but I plan to. Hamburgerpanda prints and cards are scientific-cute, if such a category exists. Cindy Yep is the San Francisco artist behind Hamburgerpanda. She says she is inspired by science fiction, nature, and Asian pop culture. I particularly like her underwater robots, like Roboctopus and Turtlebot.
