On the volunteer front, I ran a computer club at my daughter's middle school for 20 sessions of 2 hours each, teaching kids some basic JavaScript, and taking them on a tour of things like turtle graphics, L-systems, rotoscoping, and a wrote them a simple "get the coins, don't touch the lava" game engine and a text-based level designer for it.
I also took a two week gig for Girls Who Code to run one of their campus summer programs at the University of Minnesota. We used Scratch to cover basic programming concepts, and in the second week they split into teams, each team working on a socially progressive game. One of the teams wrote a two player platformer that had a male and female character. The man had fewer hazards, and picked up money, and the woman had more hazards and picked up hearts. The levels were passed by the man and woman both flipping gender-specific switches. On the last level, the woman character doesn't appear, and the man can't complete all the tasks. Genius, and from a group of middle school kids.
