I do not agree, Lazarus is not a code name. Code names are stupid. Lazarus is the only and definitive name. If you don't like eligion, don't bother about the name.
You now know about who Lazarus is, a lot of people don't. Like they do not know that Marc, Peter, John, Simon,....and others are religoius names.
P.S. Imagine the desaster that will happen when searching for something about Lazarus on google if it would be renamed.
I think we should maybe make a competition about those graphical things, like what happened with the logo of Compiz. However this should not be a priority. Functionality is the priority.
