Black shirt with orange, red, and white. The back could easily be the previous m.o logo application, or just orange -- it could even be orange/red. Red is taken from the Amsterdam flag.

Black shirt w/ orange (1-color).

Black shirt w/ white (1-color).

Orange shirts w/ black or white (both 1-color).

Last, in keeping in-line with what was done last year, here's a black shirt w/ silver and orange.

I still like my proposed smaller "maemo.org" logo over the breast, with your the larger orange & white "MAEMO SUMMIT 2009 x x x OCTOBER 9-11 - AMSTERDAM" on the back (at the size you show above).

I'm with Jaffa-- I like Quim's proposal, just reversed.

The logo over the "pocket" combined with event on the back is the most common form I've seen. BUT, that may be a US thing...

EDIT: "event" was misspelled as "even".

Here you go.

Just thinking... This would be virtually impossible due to time constraints, but taking the "rock concert" shirt as an example, it would be really cool to be able to print all of the attendees' names under the logo on the back of the shirt -- like how cities are printed on concert shirts.

Yup, this last one's the cat's pajamas... just the thing !
