Except this is the type of thing the advances in CSS are meant for. It's not a creative hack. This is people exploring the bleeding edge. They introduce new and arguably better techniques for presenting content and I also think they serve as a good barometer for progress.
Did you read the source code? They're using 50 · elements as a speaker grill. That's about as close to ANSI art as you can get and still call it CSS.
My point is: With enough DIVs you can render anything in CSS (see examples below, including an entire animated Spiderman cartoon). Does it take artistic talent to draw something with CSS3? Sure. Is there lots of effort involved? Absolutely. But worth knocking something else off the front page for?
Also: isn't this what SVGs are for? Fast rendering, resolution independence... Drawing stuff with CSS3 is a cool hack, but I don't see the motivation for this from a practical perspective.
