A seat-y looking block that can only be used by one player at a time. You can do various things depending on what blocks are connected to a seat: Ship core, weapon modules, turret docks and cockpits. A connected ship core would let you control the ship as if you were in the actual core, weapon modules would still work as they do right now, connected turret docks would let you control the turrets that are connected to them (Again as if you were in the actual turret), and cockpits that are connected to a seat can be used from it. Arrow keys to cycle trough cockpit blocks and turrets.
And let's not forget the ability to look around when in seat-view
