Posting something like this on LJ, I mean.
There's an indiegogo campaign going on right now that I have contributed to. It's for the development of a pressure-sensing device for wheelchair users, to allow them to keep track of the pressure in their wheelchair seat, to prevent pressure sores, and to help their therapists devise and create therapies to that purpose. I believe that this could a alleviate much suffering for many people and I couldn't NOT contribute. If you're interested,
go check out their video. The product is called Sensi-mat.
