From testing and feedback from users it seems that without being able to see the network there isn't much interest. The most enjoyment comes when you can see your actions influence another computer. This is something that will be fixed with larger projects when there is a response from the server back to the client.
Client --- Server
Currently all clients connect to the server and the server creates the art work.
Client --- Server --- Client
Eventually I hope to have messages back to the clients. This would add a lot of extra work and would need longer than the 3 weeks to finish so for now I will stick with the simpler setup.
