The Zen Design Group is to launch a range of children’s toys which feature LEDs powered by a hand crank that the child operates to provide power to the rechargeable batteries.

SEE Toys (Safety, Ecology, and Economy) include Dynafly, a laughing bug which moves its arms and head and whose eyes and tail light up with LEDs when the crank is turned.

“I wasn’t trying to be trendy,” said company president, Sun Yu. “I looked at my product line one day and thought about how nice it would be to not have to replace and purchase batteries. The product I wanted to make just fit into the times.”
