This was the last vacation day for laser cutter, soldering iron, drilling machine and all other tools that will have to work tremendously hard till the end of the week.

The day began with the presentation of each groups first vague ideas followed by a short discussion which idea should be realized and how it could be improved. We heard about vuvuzela traffic lights, unhittable footballs and computer mice, that force the user to ride the bike.

Armed with post-its and whiteboard markers each team spent the next hours with brainstorming and elaborating their most promising idea.

At the second presentation in the afternoon most vague ideas had become concrete concepts.

So, let’s make some noise!
