While the Ambassadors ponder over the issues presented by Vinz and
Gnokii, let us trash the design oriented part amongst ourselves.
Right now I see two options:
A: use gnokii's/tatica's characters as exemplified by Vinz here:
B: Use *I-don't-know-his-name*'s characters as exemplified here:
I was thinking in the lines of *B* but adapted to poses that can send
the 'Ambassador' message. Like Characters with 'name-tags', mic,
knapsacks, school-bags, laptops etc to represent different areas/levels
of ambassadorial activities. I made a crude sketch of what i had in mind.
[DISCLAIMER] its crude!!!
The idea: Gnokii could vectorize the sketch taking cognizance of  and
add some of his feel to it -- then everybody should be happy.
