My company is doing our annual "sneaky santa" gift exchange next month and I'm trying to think about what I want to do this year. I try to come up with "engineer-y" gift boxes just for fun. Usually the gift is a giftcard, but the fun part of the gift is the package it comes in.
For example:
Last year I put the gift card in a wooden box that had a single opening just big enough for a hand to fit into. In a non-accessable chamber in the box I put a crazy vibrator. I made this from a strong electric motor with an uneven weight attached and a battery. I controlled this with a remote that I had in my pocket. There were instructions on the box saying that they had to reach into the box to get their gift, but that elves inside the box were very upset. When someone reached into the box to get their gift I pushed the button and made the box vibrate. It went over really well.
Since I know there are a lot of engineers here, I was hoping to get some ideas from you guys. I have electronics knowledge and am fairly mechanically inclined, so lets hear some ideas!
