This weekend was mildly productive.  I resolved the memory leak in Pitchers Duel, which was actually a memory leak in Lamina.   So I put a corrected version of Lamina in subversion; I also updated the demos to fail more politely in the absence of necessary GUI libraries.

I will try to get a new release packaged up and put on Pypi this week, but the current code is available at the link below.
