realratso asks: "So it's that time of year again... the holidays. Time to choose the 'company gift' for everyone in our small programming company. We've done all the stuff with the company logo- sweatshirts, t-shirts, travel bags, glasses, mugs, etc. It all seems so boring. Is there any gift which you have received at your workplace that was super-cool, not gender specific, and relatively inexpensive? Something that was really usable and worthwhile that you appreciated, but might not buy for yourself? Maybe a new techno-gadget? (and no, 'just money' is not a valid answer)"
Quantum Mechanics is a lovely introduction to Hilbert Spaces!
