Some time ago I developed a little javascript game based on OpenStreetMap I never mentioned here I think.
Its name is OpenStreetGame and the goal is to place accurately capitals on a world map.
You can play it here : http://mcmic.haxx.es/index.php?page=openstreetgame
Anyway, I recently tested the free software owncloud and found it great. Owncloud have documentation for apps development but no-one had proposed any app yet (beside official defaults ones) so I adapted my game for owncloud.
It can now be installed inside owncloud and played by all members.
Sadly I don't have any time nor motivation to develop a highscore system that would make the integration into owncloud less useless.
The problem is that OpenStreetGame don't have any logo.
And in the owncloud menu, that makes it kind of ugly :

(there is also a problem with the name that is too long for the menu, but whatever…)
So, if someone here would be kind enough to provide a logo (under a free license of course ;-) ) for OpenStreetGame that would fit nicely in the owncloud menu, that would be great.
PS : oh, and if you want to learn more about owncloud : http://owncloud.org/index.php/Main_Page
