this shows an interactive graphical program working with shed skin :-) the user can drag around points, and the connected 'bodies' move around realistically. to get this to work, I had to add basic pygame support (drawing points , lines, event handling). doing this was an interesting experience - I now feel it should be not too difficult to autogenerate bindings to many libraries, based on 1) a simple type model (manually written, see *_.py) and 2) the results of type inference. because my job requires me to implement/bridge some library calls, maybe I can be paid to work on this. hmm..
