line and texture

1. I took this photo at the drinking fountain, i love how the water is flowing together
   it may look like a solid line but it is water as you know water isn't solid...
2. This photo is a drain, the corrosion has a texture over the lines which the shadows make the the bright sources stand out...
3. A hole in a tree can have line and texture, shadows and lights but at certain times of the day the sun will show you the true texture to nature...
