As the title says it’s a video of the awesome freeware video game Dyson. Give it a few minutes before any action happens. This game is basically a virus simulator. The official premise is that Dyson is a colonization game where you take a set of self-replicating mining machines and attempt to gain control of an entire asteroid belt. It would be nice to see some difficulty settings or multiplayer.
Anyways you can get the game here.
This is why they chose the name. Very interesting stuff.
