Hi all,
I've just finish 3 versions for the Wikidata logo. I can't currently upload images in Wikimedia then the images are available here : - http://dl.dropbox.com/u/177440/wikidata/20120404_wikidata1.png - http://dl.dropbox.com/u/177440/wikidata/20120404_wikidata2.png - http://dl.dropbox.com/u/177440/wikidata/20120404_wikidata3.png
I've also introduced my work in the talk page here: - https://meta.wikimedia.org/wiki/Talk:Wikidata#WikiData_logo_candidate
