Please, please, please do not use skeuomorphic spinning knobs on your web pages. They're horrible to use. Right now you're thinking, "but if you implement them this way, they're fine!" No, no they are not. Physical knobs work well because we have opposable thumbs. We can roll the knob between our thumb and forefinger in a way that provides gratifying tactile feedback. There are no methods to achieve this with a mouse pointer interacting with a knob.
