[Numpy-discussion] visual programming

[Mathew Yeates]

semi off topic.
Does anyone know of any good visual programming tools? Forever ago, I 
used to use something called Khoros for image processing and I found it 
very useful. You connect boxes which represent different processing 
steps. At about the same time, there was something similar to Khoros 
from SGI. Explorer was its name, I think.

Anybody out there use this sort of thing? Matlab doesn't offer it, 
right? Nor matplotlib?
