Texture represents an object's feel or consistency. You can feel the glossy texture of your computer keys or the slick condensation of a glass of water.
But take a look at these 20 photos. You can see texture, too. From the stickiness of an old piece of gum to the fuzziness of a spider's skin, sometimes you can see the texture of an object almost as well as you can feel it.
For this week's Mashable Photo Challenge, we wanted to explore the visual side of texture. So we asked our readers to take a close look at the world around them.
Readers sent in all kinds of close-ups that show texture. We selected 20 of the best texture photos that we think communicate how these objects feel or what it would be like to touch them.
