Like others have mentioned here the demo seems to be able to categorize users into certain groups, but it is unclear how useful it is for fingerprinting and track an individual. I would love to see some statistics on it because from the data the demo gathers it seems like it will have a hard time to make out individuals in many cases. I find the technique used in the paper "Prime+Probe 1, JavaScript 0: Overcoming Browser-based Side-Channel Defenses" [1] more interesting, although highly impractical. I guess there might be more practical CSS-based techniques that could fingerprint an individual and track them over several sites, but I have a hard time to see the limited tracking presented in this article would be very effective.
