Lined paper, a photo by stst31415 on Flickr.

I tried to shoot another macro but wanted to use a different light. A bunch of paper was used – you can see the edges and lines of the paper.
A white LED was the light source from the left and a laser pointer was used from the top and aimed between the paper.
In post processing I used the tonal contrast filter from Nik Color Efex. This enhanced the edges and enhanced the abstract effect of the picture.
I can imagine this quite good on a wall.
