What is Orb.Farm?
Orb.Farm is a falling sand style simulation of a sealed glass orb that you fill with your own little underwater world. You pour in sand, stone, wood and water, then add living things like algae, grass, bacteria, tiny daphnia and fish, and watch how they interact.
A gauge shows the balance of carbon dioxide and oxygen, so you can see whether your ecosystem is thriving or slowly collapsing. A short tutorial with a cute pixel daphnia gets you started. It is relaxing to watch and quietly teaches how food chains and gas cycles keep a habitat alive.
