Nice hunt @anomalogy!

This is a great invention to gain back use in the hands of the users which has had a lot of positive reviews from patients who have suffered from various strokes and gained some good results from using this device.

It is intended for use with
Stroke
Spinal Cord Injury
Cerebral Palsy
Traumatic Brain Injury
Neurologic and muscular injury
Developmental disability

What a fun way to recover too, getting better by playing fun games (that has to be more fun than squashing a squishy ball or something).

I wonder if it could also be used as a controller for simple third party games or a mouse or something else, who knows.

Priced at $349/£267, it would be a tad expensive just for a simple controller but, if it does what it claims to do and the reviews are genuine then, I guess that would be a small price to pay to get some sort of relief or improvement.
