Well, I'm not doing anything crazy with the monitor. But I'm using the Lusid plans, so the control panel with be sloped. I'm going to need some way to mount the guns so that they're level, even though they are mounted on a sloped panel. I'm not sure what the best way to do this is, though. Any suggestions would be handy!
The angle that the gun bases are pointed at is like this / \ is because that way whe you point the gun's left or right, you're pointing at the edge of the screen and you won't be pointing offscreen, which helps maintain the illusion that the gun is firing something at the screen.
