You can see below the poster for the Transylvania Flex Group event (it will be on June 6th, in Cluj, Romania). I think this is the coolest poster I ever saw :).
As a matter of fact, I challenge you to send me Adobe User Groups logos/posters, if you think they are better than this one.
PS. I am sad I will not be able to attend this event. My fellow evangelist, Cornel, will be there. But I am happy, because the guys from Transylvania Flex UG promised me that they will send me a T-shirt with their logo.
