hi hi hi
this is the only one place on the world wide web where you can animate a 3d girl with your eyes!
how?
It uses an eye tracking library WebGazer.js that detects where are you looking. The butterfly is a location of your gaze, the girl rotates her waist and head trying to watch on the butterfly.
To make it work, you have to train this model by clicking on stars that will appear after the start.
