Debby Elnatan's son Rotem has cerebral palsy and is bound to a wheelchair. To help in walking him around, she invented the Firefly Upsee, a harness that holds a disabled child to an adult's legs, letting the child walk as the adult walks.

Buzz around the Upsee, priced at about $500, has taken off as its April 7 launch date approaches. See it in action in these promotional videos.
