I remember playing with this at least 8 years ago. It's really scary that there's enough information disclosure in browsers that it's possible to do this.
This is really scary to you? I get that you can do fingerprints, and honestly there's a LOT more than just browser window position/size in them, but "really scary"?
Maybe we need to stop exaggerating on this sort of stuff if we want people to take us seriously.
Fine. It's scary that browsers allow for so much fingerprinting. This toy webapp is an example of a larger picture of "things that we really shouldn't allow to happen". So "really scary" was referring to the issue of browser fingerprinting as a whole, not just one toy webapp.
