Bungie's 3d artist, Travis Brady
If you use the two Teleporter in Forge on Standoff, you can get out of the map, and then watch it and go further in Theater mode. When you do this, go over to the closest Satellite dish. If you look on the platform below the dish, you can see a man. It is Travis Brady, a Bungie employee who works as a 3D artist. Note that he appears on every 3D Satellite Dish.
