Re: pic: Helical Gears?

it looks like the photo is a small part of a larger picture, and this section was enlarged with photoshop or some other editing program.

When you scale an image up the program has to make assumptions about what is between pixels. Sometimes you get aliasing, and patterns are created where there was no pattern in the original photo (in this case, diagonal lines).
