Avatar/signature that depends on time, or whatever...

No. Not another avatar/signature thread.

All I want to know is wheter is would be possible to create an avatar or signature that changes with the time.
For example: An avatar with a sun on it. And that sun goes lower and lower while the evening arrives. Then, about 10 PM, the moon appears. And the next morning, you can see a glimpse of a sun.
Would that be possible? For example, using a PHP-script?

yeah, but only for your signature. you have to have webhosting that supports PHP and dynamic image creation, though. try starting here (http://hotwired.lycos.com/webmonkey/01/21/index4a.html). make sure your webhost is fast though, or everyone will get mighty pissed off as dynamic PHP images can take a while to load, and that'll slow the page down.
