In a bid to attract attention, a lot of web masters use roll over animations. So, say if you roll over a button in the menu, it might change colour. this can also make it clearer to use. Whilst I'm glad Webeden has this feature on the menu it has it on nothing else. Things like shapes, images especially, could benefit from this. I don't mind having a different versions for images - Maybe when rolled over or clicked the image changes to a different one (perhaps the same but recoloured like menu bars..). It adds use-ability to a website and does not distract the visitors often.
