Would that play be Copenhagen (https://en.wikipedia.org/wiki/Copenhagen_(play))? If so, I highly recommend the BBC adaptation with Daniel Craig as Heisenberg, Stephen Rea as Niels Bohr, and Francesca Annis as Margrethe Bohr.
This project looks interesting and although I don't have much time to get into it at the moment I'm mainly commenting to create a personal bookmark for it and to thank you for sharing your project.
Please consider moving the project to a hosting site like github which would make it easier to track updates to it and easier to find in the future. Thanks again!
The benefits of dynamic languages are not their speed, its the rapid prototyping and interactivity they provide once the prototype has been designed it can be implemented for speed in any lanuage providing the features you need.
