Assistive Technology for People with Physical Disabilities

I found a really inspiring YouTube video by the Tetra Society of North America. They are a group of volunteers that engineer assitive technology for people with physical disabilities. All the clients are responsible for payment is the cost of supplies. The video shows various projects the volunteer group worked on to better the lives of people with physical disabilities. Some inventions are as complex as a hydraulic wheelchair lift put in a home, or as simple as attaching straps to a hockey stick so that a father could play with his children.
