Showing off! need some posters

Hi there all,

I have just moved my course from PICAXE to Arduino, and students are loving it. What I would like to do is put some Arduino posters around the room.

Secondly, our school is having an open night shortly for prospective students. My area is science and while I will be in a lab for the night it is not where I teach electronics. So I thought I could be sneaky and take a few Arduino themed posters with me and stick them up for the evening (obviously a working project would be better).

Anyway, I have had a bit of a google and found some suitable stuff but it won't print properly. And being a teacher, I really haven't got time to be playing with print files etc.

So if you have anything I would most appreciate a copy, and in return I promise to add at least one poster from me.

Many thanks in advance if you can help
