Algodoo

Orthographic projection is a miracle. You can use it everywhere to turn 2D into 3D without changing the program itself!
So I tried to add some depth to Algodoo. I made the background totally green without clouds and added two planes - the equator and the prime meridian. The equator has a collision layer, so everything falls near it. The prime meridian has no collision detection. I also added some clouds "above" the plane. I will release the assets later. Enjoy
