Acting is the building of human behaviour. Getting to know the different layers of our own behavioural plans, learning how to approach them and developing behaviour from simple functional units over first sequences to full co-constructed multi-agent scripts is a unique approach to gain a deep understanding of ourselves and of all that is human. This, besides being of serious value, nourishes our inner homo ludens as it offers all the joy that creative, exploratory and poetic activities have to offer. It’s all so useful, but in the end it is just so much fun.
