It’s called ToonDoo As An Educational Tool. In it, each day he shows a cartoon strip that helps define a new word. Intermediate and above English Language Learners would find it useful.
He was also involved in creating an older site called Jambav, which has a number of well-done online educational games for young children.
I especially like (I think my Begininner students will, too) its I Spy! and Spell Pix games, though the I Spy! game had a technical glitch which I emailed them about. With luck, it will be fixed quickly.
