A long with some of my work colleagues we recently built a jQuery Dial/Knob UI control that we decided to open-source and share with others. We tested it against the following browsers:
- Chrome 23
- Opera 12.11
- Safari 6.0.2
- Firefox 17
- IE6+
Check out the project page, for instructions on how to use it and a working example. Let me know about your thoughts or indeed any issues.
