The flat earth simulator was taken from the STEAM gaming online program. I’ve found it very interesting and decided to make a video out of it. It has a very good introduction to the Flat Earth Theory. I did some little experiments at the end, hope you’ll find them interesting as the flat earth simulator allows you to play with the sizes of the Sun and the Moon, distances, views, etc.
