You can either copy the source code or e-mail me for the zip file.  I'll be happy to assist.  By viewing the source code, you will find a link to the coding for the fish and bubbles script.  If you want the files to complete the effect as you see it, e-mail me for the zip file.  If you would like custom graphics made to match this set, I'll be happy to help.  There is a blank icon, complete w/mouseover for your use.  The font used for the banner is "Dyecut".
