The update is expected to be live in both the App Store and Google Play in a matter of hours. In the mean time, check out this video of the graphics in action.
For any Python and Kivy folks that are interested, these graphics are generated using a fork of the kivy3dgui library. There were only a few minor changes; I used a different glsl shader than the default because the initial one crashed on iPhone. Also a few minor syntax bugs that popped up, I suspect just a difference in Python version from what was used to create kivy3dgui versus what I'm using.
Other than that, the interface and simulation engine are all the same as before.
