So, here are two pictures of my (passive) intake, that is capped off with a 'dust shroom' that I got on Amazon.

The first picture will be lit, so that you can see exactly the shape that the ducting is formed into. The dust shroom is claimed to be a zero cfm-loss cap, which eliminates dust, hair, and can help prevent mold/mildews.

The second picture is set in the exact same place as the first picture, but with the lights off in the room that the tent is set in. You will be able to see the light radiating trough the insulated ducting slightly, which will demonstrate the way the light trap is working.
