Love that! Not many folks will notice, but those that do, it will make their day (or make their skin crawl). Speaking of which, there's two or three Easter Eggs in this app as well :)
Glasses can now be set to any color you want. Only applies to the "Classic" style, though. Unless I find the other glasses in SVG format as well.
As a nice side-effect, the glasses can now also be set as semi-transparent!
On mobile it should work too (at least when I tested on recent iPhones). The drag handle is a bit small, though. Just aim for bottom right corner of the glasses.
