When browsing static/non-animated web pages, sometimes I get a feeling that the developers wanted to draw, had to make a website instead, and tried to combine those two, so users are then forced to appreciate their art. But with animated ones it's rather like making a game -- and once again the users are forced to run and complete it in order to proceed to what they were after. Good that it's optimized (although it's still a 60% CPU load and laggy here), but I'm rather curious how it may seem like a good idea in the first place.
