WebGazer.js is cool but, it is not even close to the Tobii for accuracy.
@Jenny, @John My first post..
I have to agree with @John an official Javascript API would be awesome. Third parties are cathing up faster and I think it should be the otherway around.

Same goes for Java API and or Processing Plugin. OpenFrameworks implementation also seems to be third party.
Anyway still love the eye X 🙂
