Basically what I want to try to create is similar to this:
I've downloaded molecular and cube surfer.
I don't care about the reflections, colors etc. I just want to try to recreate the physics.
I think I need to create an emitter which produces all the balls into a grid. But then I also need to attach this to something, so it won't drop - plus I need to make so other objects can drop onto it and make it move.
I'm lost. Spend the last two full days trying to wrap my head around this.
