More shots/User testing

These screen prints show a more refined version of my experimentation. I have gotten to a level whereby you can insert a planet, change the colour, size, orbit radius and position. 

I have asked a few people to use the programme and a few issues have been raised. One is that it is unclear that you have to rotate the marker in order for the planet to react accordingly. Another is that some of the different changes aren’t satisfying enough, I may think about adding arrows to the markers themselves, and also sounds to increase the feeling of doing something as you rotate the marker.
