Just wondering who made Electropus and if he/she has any particular license?
UPDATE: I spoke to Maddy from Little Bird electronics on the email and she thinks that the design originally came from 99designs.com - So I might not find out who made this image in the first place. Maddy also informs me that the image was sold along with Chiphacker to the Stackexchange guys. I'll have to give them a nudge and see what they say.
