A small development group backed by AdventNet is doing an interactive kids site Jambav for kids. The focus is on educational/entertaining interactives. It is meant for regular kids, 4 and above, and with a special focus on special needs kids. What does Jambav mean? To quote the Jambav site http://jambav.com/jambav/aboutjambav/aboutjambav.p hp:

We call ourselves Jambav, after the king of bears Jhambhavan of the Ramayana. He was the spark that ignited the “sleeping“ potential of Hanuman who had been cursed into a state of forgetfulness by the sages.

The effort started around a year ago, and has put out some nice interactives. My son uses it occasionally, but as he grows older, we hope to use it more and more. The Jambav team is working on more tools.
