i live in bulgaria. I am rather doubtful that any prize would get shipped here.
I like your t-shirts idea.
Vector linux logo needs more ideas and freedom for improvisation in order for an artist to create something original,like original content to boost popularity.I did some comical wallpapers in the past (check my kde-look (im blurymind there too))
Maybe you could slip in some developer humor and with some more drawing skills make it look cool
Thats why many distros have a mascot,and not only a logo...or if they do have a logo,it means something more than what it looks like.
I proposed a silver rocket as a logo idea,or atleast a silver rocket with the v planet- there is some retro sci fi vintage there...
You need to somehow hint an artist,to tickle their imagination very hard.To do that,you need to create some soul for the product.
also you need to be more specific as to what is expected from the participants..and leave them with lots of freedom to do whatever they want,but associate it with VL.
also would be a good idea to actually go to some artist comunity,instead of our little forum here.If i was to start an art contest with real prizes,i would definatelly go to deviantart,kde-look and the other *-look websites and promote the hell out of it.
anyways,shouldnt this topic be in the art section of the forum that is almost a wasteland these days
if not an art project,it could be many other things...but you need to look for a common skill in this comunity
