There is a pretty recognizable visual entity associated with breast cancer, obviously the pink ribbon, and I think that this would be a great idea especially since October is Breast Cancer awareness month. However, I DO think that there should be a donation system, and Bungie has already set up means to do it. Put it up for sale in the new store, people can by it with real money (perhaps a dollar) and donate all the proceeds to the foundation. It could be implemented for whatever charitable organization anyone wants going forward, or make it an annual event. Most organizations support a couple of different ones. I also think it would be fantastic to do Movember for prostate cancer in November. Have moustaches available for sale in the store, again for a dollar, and all proceeds go to prostate cancer research and men's mental health issues. I like this idea a lot.
