I finally thought of a chalice/logo for UUpdates. The image is very basic chalice with two portions of a circle surrounding it. Lest anyone think that the partial circles are a theological commentary I will point out that it's inspired by the Live Bookmark button used by Firefox. For an explanation of the logo (Firefox's not mine) check out this post. I wanted a similar idea.
In case it changes on the site in the future here is the version I am talking about.
I am not a graphic artist, I was inspired but this does not imbue me with natural talent for graphic design. If you do have such skills and are so inclined I would truly appreciate someone taking the "radiating chalice" idea and making something that looks really nice.
