You're misquoting my quote ;) The sentence fragment I'm addressing is "...the Qi Hardware cites just four other projects that follow the same approach: the Elphel digital camera, Pandora game console, the Milkymist One visual-effects video synthesizer, and the Arduino microcontroller."

To clarify: there are more than 4 (or 3) other projects. I wish the author had looked a bit harder instead of using only the Qi website!
