How you can design a web site with minimum screen and color depth problems.

I have found that you can aquire information about a user's screen
width, height, and how many colors they have on the screen by using
Javascript.  But little does that have any valid use for the
webmaster, since it is client side, or is it?  I have written a script
that will pass along this information into a CGI Program.  That way it
can be gathered by webmasters for making design decisions.

See An Online Example.  You may have to configure it to your own
personal needs.
