I would like the following ... I want to have a clock that shows the hours when someone is available. For example if they are available at 1 and 3 there would be a green "pie slice" at 1 and another at 3. I dont want different images as all the combinations would be unmanageable so I was thinking a clock that is blank(transparent) with CSS z-layers at the different available times. What do you think? This must work with relative positioning so that I can put anywhere on a page. The size of clock should be around 300x300 - maybe slightly smaller.
