I read this article about a man in Montana who has been building special game controllers for the disabled for like 30 years now.

The problem is that when he eventually stops building these controllers (and he is 70 now), no one will be there to take his place. As Ben has a reputation for building controllers for those in need I thought maybe he might get in touch with this man and do .. something cool. I don't think there is any profit in this but it seems like a Ben kind of thing. Oh and an episode of the Ben heck show about tong controllers and air sensors would be really cool.
