I have a (very) small amount of physics code done and thought I should mock up the gui to work out what I would need to put in and what I will need out of the simulation.

I have completed the physics simulation and continued work on the UI today although it is still somewhat lacking and I think I'll have to make do with the short version of my game for pyweek.
Here's some graphs produced from the output of my simulation!

Didn't get as much as I should have done today but I fixed a bunch of bugs in my physics, got orbits showing up and the screenshot. I've also made a crappy little spacecraft image. Next I need to get the craft on the screen and an arrow for the velocity and get those changing on variable change. I'm also thinking about switching the direction vector to just an angle of rotation. I also need to finish the rest of the dialogs and add pop-ups if you're going to crash or explode. Title screen might be good too, some more graphics, sound effect and music...Maybe have to skip one or two of those. Oh well. I want to finish on friday so I can just test on saturday as I'll have access to other OS's but not a lot of time for development.

I hope it works for everybody. You might need pyglet, kytten and cocos2d if I didn't attach it properly. I'm quite pleased with it but it definitely needs more time.
