Friend acquires a lot of cheese. What to do with it?

For complicated / irrelevant reasons a friend has suddenly acquired 18 pounds of Red Leicester cheese. It is good quality. However (again, complicated reasons) the cheese must be moved, used or transformed into something else within the next 72 hours or so. [more inside]

What can you see?

My boyfriend is legally blind. He was born with cataracts in both eyes and has moderate to severe astigmatism in one of them. I'm struggling to get some idea of what he sees. [more inside]

Perspective drawing calculation

If I want to draw something in one-point perspective, say, like a set of railroad tracks where the vanishing point is on the horizon, and the tracks are represented on the picture plane by an equilateral triangle (they appear that way to the viewer), the apex of the triangle being the vanishing point on the horizon and the base of the triangle is where the tracks meet the picture plane, how do I calculate where the railroad ties would be? (Given that in 3D they are evenly spaced. Also, I'm not really concerned with the thickness of the ties -- we can consider the ties to simply be horizontal lines.) [more inside]

Great big gods, teeny tiny temples!

Why did all the supposed-to-be-massive sets in Immortals 3D look tiny? Did it have something to do with the fact that it's a 3D conversion? It was like the whole thing was shot in tilt-shift. [more inside]

3D GeometryFilter: Is there a mathematical equation that defines relative lengths of objects at different depths of field for humans?

Is there an equation that defines the change in apparent size as a function of distance from the viewer? Basically, if I'm looking at a set of railroad tracks head on, if one plank is like 10 ft away, it appears to be one size. The same plank 20 ft away appears smaller. What is the relative size difference? Put another way, how big does a 1ft line appear to be at 10 ft, at 20 ft, etc.? [more inside]
