There are four parts to the workshop. The first part simulates a multi-hop dynamic routing ad -hoc network as a set of physical instructions based on simple rule-sets. People "play act" as nodes of a network (which builds on a core concept of ad-hoc networking, where people literally 'are' the network when equipped with small wireless communication devices such as handheld PDA's.) Following this activity, we discuss multi-hop dynamic routing ad-hoc networking concepts as they relate to the previous physical exercise, and distinguish the technology from other types of wireless network infrastructures to promote understanding and to raise awareness of the unique opportunity for research and creative practice these types of networks afford. The third part of the workshop is a participatory design test of the 'Oscillating Windows' prototype, which allows for basic customization of certain network communications parameters. This allows participants to experiment with a working multi-hop dynamic routing ad-hoc network, and to highlight any emergent uses or desired functionality of the system. To conclude the workshop we gather feedback and discuss possibilities for further collaboration and development.
