Wikisource is a bit funny. It is an iceberg about to keel over. It has been the logo used on most Wikisource projects and apparantly I am not the only one who does not like it.
According to the bug 33907, the plan is for the Marathi Wikisource to have its own logo. It is very much a logo for the Marathi Wikisource and it needs some adaptation when it is to be used for the Gujarati Wikisource.
What I would like is to have the logo for Wikisource revisited. The Marathi example is more obvious for a source project. It beats an iceberg that reminds people of the Titanic any day.
