From the developer:
The ExtendSim is a limited, non-expiring, working copy of ExtendSim that includes complete manual sets (in electronic format). One of the great things about this is that you can actually build dynamic models. Explore ExtendSim capabilities with the pre-built models on this... then build your own! You can also use it as a Player to view models built by other ExtendSim users.
