My company just released a long overdue software product and it has gotten fabulous reviews. My boss asked me to help pick out gifts for the engineering teams. We got some tchotchkes from Think Geek but I need something less than $20 each we can give out to the developers. We are giving gift cards and t-shirts as well.
I want something fun like a desk toy that they would play with but it needs to have "geek cred."
