Thanks to all replies so far. The idea here is to elicit some sort of expression of interest from graphic designers and artists. This is fairly normal in larger competitions - at least we know there will be a few quality entries. It also gives longer time for the designers to have a think.

There is a problem of posting in both the mathematics and art forums, but that can be resolved with an index-post.

I'm thinking of a prize of some 25-40 SBD. We're still a pretty small trail!
