Portal Design (10) Laser-pointing devices and eyecam

I wanted to create a challenge involving turrets firing not at the player but at locations like a moving ball or a fixed target. Then putting the turrets out of ammo made me think that I could use laser pointing devices as a gameplay element, the turrets out of ammo draw it's laser blinking, and the laser go through portals. So I used the rocket turrets, turning them into pointing devices. So now I got them two, blue lasers pointing and red lasers firing at a dead body floating on water. Then I told myself "Hey? Can I use those pointing devices to make a camera viewable by the player?". So I did it.
