I want an header image to use on my blogs http://raphaelhertzog.com and http://raphaelhertzog.fr. The current header size is 960x100 but it can be higher (e.g up to 960x180). On the right half of the picture there might be some widgets that hide part of the picture so any visual on this side should not be too important for the message that the header conveys.
I would like the banner to illustrate the fact that this is a place to learn/be taught about Debian and Ubuntu. Both the Debian Logo and the Ubuntu logo must be apparent somewhere in the header. The Debian logo should be more visible that the Ubuntu one and/or play a more important role in the message/metaphor. The title of the blog should be integrable/integrated in the picture somewhere (remember that I want to use the same picture for two different blogs speaking of the same thing but in 2 different languages).
Bonus point: the Debian project has an ultimate goal of "world domination" (that would be reached when every computer on the planet runs Debian) and it would be fun to illustrate this "prevision" in the picture. This is only a bonus, it's more important to first convey the messages that this blog is place where you can learn new skills related to Debian and Ubuntu.
Given the title of the English blog ("apt-get install debian-wizard") it might be a good idea to build on the "magician" metaphor. For example a magician could use his wand to "convert/transform" a computer into a Debian-powered computer, and this computer would "generate" lots of small "Ubuntu" that would conquer the world.
Note that this idea builds on the fact that Ubuntu derives from Debian and that Ubuntu is more popular than Debian.
But this is only an idea, by all means feel free to try out other things, I'm definitely not someone "creative" when it comes to representing things graphically and I'm not necessarily attached to it.
I've attached the header image that I used before I switched to the current theme just to show you "the spirit" I tried to give to it. Note that this sample uses a dark background because it used to fit well in the context of the TwentyTen theme in use at that time. It's not required to keep a dark background and in fact it might be a bad choice. This was a simple background created with The Gimp because I'm not an artist, I'm looking for something more elaborated now!
