Data hidden in the flicker of fluorescent bulbs may help the disabled lead
independent lives. 

The flicker of fluorescent lights, long a symbol of institutional drear, may
give new freedom to the handicapped, thanks to a high-tech startup that sees
the bulbs as the perfect transmitters. 

Talking Lights, a Cambridge-based MIT spinoff, is developing a local area
network that uses fluctuations in fluorescent lights to transmit data.
Inventor, company founder and MIT professor Steven Leeb predicts the
technology will be a boon for the disabled.
