The "move the ball around with your eyes" demo doesn't work at all for me in Safari on a MacBook. I can only move the ball with the mouse. The other demo works okay, but very low accuracy (like 50%). Firefox on the same computer is unusably slow, generates a new "data point" (the visible dot) only every few seconds. Accuracy was about 10%.
