At lunch today, the whole company split into 4 teams and we played an Agile game called the Marshmallow Challenge, in which each team had a marshmallow, some spaghetti and some string. The task was to have the marshmallow as high off the floor as you can within the 20 mins, the structure had to be freestanding. The point was to start simple and then build on it. Our team was doing well, but then it all fell apart as our time ran out. It did reinforce the agile principals though.
