Last December I organized Toy Hack SF. We took regular toys and rewired them so that they could be activated by a large, single switch. Why? For many kids with physical disabilities playing with off-the-shelf toys is not possible. Depending on their unique abilities, a toy might not be accessible. However, if a child can move their head, feet, arm, mouth or any other part of their body it is possible to use a switch to play with the toy.
