Workshop Arduino in HardMeeting2010

What it should be an intimate 10 assistant arround a table workshop , becomes a a more than 30 assitants macro-workshop with loudspeakers,  here you have the  slides and examples(in spanish) , more pictures and video inside the post.

The pictures are from the "main" table, there was three aux tables more :)

I was unable to stand just in front of the slides :P

The most special moment for me was when the some assistants succed in the example of the "death roulette" with an Arduino Mega and Arduino Duemilanove, is a simply game to demonstrate the serial comunication between Arduino boards and also test the  reaction speed of the attendants :)

What to say , I enjoy it a lot after the first doubts of where to put so many people :)
Here are the  Hardmeeting videos  including the workshop
If you have more pictures/videos of the workshop please put the link on the comments, also I would like your opinion to have it in account to future workshops.
See you on next one :)
