We played CatchBob! on this sunny afternoon. It is pretty robust now that we got rid of the VPN problem. Positioning is fine, as represented on the picture, there are few errors but it's OK. The only problem is when we tried to form the triangle to "circle" the object: it is difficult to see the very triangle and to have a real "end condition". We're still working on it. We also have two logfiles (client and sever). I am learning how to use python to parse this so that we can get the expected indexes for the statistical analysis.
