You're right, some samples are composed of several smaller samples (like the geometry_demo.py). Each of this sample is a function that is added at runtime to the GUI.

I should have written 'it certainly can be done from a pipe' (open an ipython session and send command with the sys.stdint, just an idea). Loïc > Thomas
