New to the concept of OSC, and having never heard of TUIO before, I tried this app. Within five minutes, I had a Labview app working to read the data. A few hours later, I had a working remote mouse script.
This app has a very simplistic interface, with very simple options. It launches and connects quickly. It provides a very good base from which to test the TUIO protocol. The shake-to-exit method is a bit annoying, but not much of a problem. All together, a very useful app.
