Similarly, we've been using lighting and depth effects with text on the web forever. Not everyone subscribes to the everything-must-be-flat-and-boring aesthetic, and if you want these kinds of effects you can do much more with a good graphics package and 16 million colours than you can in any monochrome font design, enough if it does have an elegant underlying form and it was made using some clever algorithms. It's seems a pretty enough and well constructed font, as with much of their work, but I'm just not sure when I'd use it.

Douglas Hofstadter put some interesting thoughts on the parametric knob-twiddling approach to fonts and other domains of creative expression here:
