What the close-up? #1

Today I'm going to try a little blogging experiment. For a while, I've been considering some kind of quiz format where I take a picture of something, crop to just a texture or shape, and have you, my readers, guess what the object might be. Frankly, I'm not sure how fun it will be, but I figured we should give it a shot. If you are in favor of this idea, the best way to show your support is to participate by guessing. If popularity drops to only one or two guesses, then the idea might have to be discontinued. Let the games begin!

I will post the answer and the winner one week after the original WTCU post, with the chance of a possible clue mid-week if no one is close.

The image has been desaturated to highlight only the texture. Can you guess what this is a photo of?

Disgusting hint: it's not a part of my body.

Answer

Winner: Paul Runner-Up: Simon

I agree with Simon that it's pretty ambiguous as to which citrus fruit this is. It could very easily be a lemon or grapefruit. But Paul wins first prize for having the lemons to commit himself to just one type of fruit. The correct answer is, of course, an orange.

Hence the need to desaturate the image. With the color information it would have been too obvious.

Thanks for playing. Try What the close-up? #2.
