How to create a logo that automatically changes every day?

[Todd's keyboard]

How would one go about creating a logo for a web page that changes color every day?

I'd like to have a logo that is mostly gray scale, with a small patch of color. It would be nice if that spot of color could change hue every day.

If I understand correctly, colors are the Internet are given numeric values. One approach might be to assign a transparent space in the logo, and then have a different file with a specific RGB number superimposed on top of that transparent space. Then write a script so that the RGB number increases by one every day, until it cycles through to the original number again.

Any thoughts on how to write a script to get the RGB value to change automatically every day?

thanks, Todd's hue-challenged keyboard

Using PHP it's not too tough.

PS. Hit refresh and watch my sig change colors!

FWIW: sig is not changing colors for me on multiple refreshes( is that a word?), althought I remember seeing it red a few times.

You can also do it swapping out graphics in Javascript. There are scripts on the web.

Changed for me the first time in Safari

Any server-side scripting language can do this easily with either the GD or ImageMagick libraries installed. Or you could use a client-side javascript.

Your actual logo, which elements of it, and how many iterations you want to create will determine which method you choose to use.

You could probably use Flash as well.

pretty easy in flash I think

First guess, I'd probably just choose a random number for each of the R,G,B values and tint it the resulting color.

That is why the view count is so high on this post the refreshing SIG....

How refreshing! Sig chaged for me (Camino).

Forgot to mention I was on IE 6 PC today at work when it wasn't changing. At home on Safari it changes as everyone else reports.
