I am currently putting together a water related website and I would like a banner that has a water theme to it.
Sounds great, but can you give us a rough idea of how big you want it? Also what text would you want in the design?
I've created a simple flash banner. You didn't specify if you wanted a static or flash banner. If you don't want it as a banner you could use it as an advertising link (with a few modifications) from other sites. You can view it at this link http://turns.i8.com/waterwise.html
