Welcome to TIME! This is a completely pen rendered clock! There are several different modes, so press space to toggle between the different styles. There is the digital time in the bottom left corner.
If there is lag, move your mouse onto the screen or just move it at all, and that might solve some of the problem. If that doesn't work, press space until there is no gloss on the clock and no digital time in the bottom left corner.
It works fantastic here! http://phosphorus.github.io/#99957224
