Hello art folks!
SpreadUbuntu is on its way! Attached is a proposed sitemap you can see a detailed writeout of what the project is supposed to fulfill at https://wiki.ubuntu.com/MarketingTeam/SpreadUbuntu
What we need now are design proposals.
For those interested in making a design mockup, I'll quote myself from the mailing list:

For now, I'm looking for a front page in the Ubuntu colors, with a block
of structured text (we'll use the one below from ubuntu.com for this
mockup) and in-text links. If these look good, there's no harm either.
What should be dominant _after_ the text are five big colorful links for
See it, Try it, Get it, Shipit, SPREAD IT! Since Try it and Shipit might
not be available, be sure to make it easy to remove these and/or modify
them. One thing to keep in mind is that once the user leaves this index
page, some sort of navigation toolbara should be available. Don't make
this now, just make sure there is room for it to pop up in your design
whenever not on the front page (suggestion: instead of a Spreadubuntu
header, or two versions of the header: big font & small font + navigator).
I'm in favor of elegant and smooth designs rather than sharp and vibrant
ones, but do as you can best.

I'll just add: it has to look new and exciting, to draw the user into thinking they've found something that'll change their computer life for ever... and all that jazz - you guys are the artists .
