Been there, done that, designed the T shirt - a creative challenge promoting the conference or company message. Teams are provided with a plain white T shirt for each person.
The challenge is to come up with an imaginative, creative and unique design which will promote themselves, a product or the company. They will need to reach a consensus of opinion, and humour will naturally be well rewarded.
A fun and interesting way to get across key messages and a chance to see your colleagues in a new light!
