The Gray Area Foundation For The Arts (http://www.gaffta.org/) had a workshop for teachers of middle school students. They created a nice gender-neutral bracelet for sports fans using BlinkM MinMs (http://minm.thingm.com/)
As Grace says: "The workshop went well. I had two teachers as my students, one who teaches middle school and one who writes curriculum for a children's camp. They were both very interested in the MinMs and their potential to be used in teaching. One issue that came up was that one of the teachers was trying to come up with a gender neutral design and decided to make a 49ers wristband and wanted the LED to flash red, then yellow. However, we realized that there was no way to create a true yellow. We were able to get around it by covering the LED with yellow felt, as you can see from the video."
