Lot's of fun it was.
Soon the new Arduino Jam is about to happen (From 21 till 23 sept 2012), and I entered right away. I even decided to sponsor the event. Why, because I happen to find things like this, fun, lots of fun.
So, if you live in Belgium or the Netherlands, join us and enter the jam. You can't, but you would like to take a peek, you're welcome too. And if you want to sponsor the event, well just fill out the form.
