Culture hacking in action: shared resource

It seems there shouldn’t be a problem. If it’s a dedicated projector for a meeting room, why should you take it and don’t bring it back? But crowd behaviour sometimes is weird and unpredictable even though everyone alone is a very sane and smart person.

What did we try?
- Emails explaining the situation. Did it work? NO!
- Talking in person by a coffee machine. Did it work? NO!

Decided to try another thing - infographics and visualization. Do you think it will work? What else could we try? (e.g. nailing stuff to a table? :))
