This is another photo similar to the one I posted yesterday. As you can guess, it’s a fingerprint-mine to be exact.
I actually design pens, highlighters and markers for a living. As part of my job, I need to take apart and rebuild products for testing. The last time that I had to do this I got highlighter ink all over my fingers. While using a digital microscope with a UV light I accidentally snapped this shot and thought it looked really cool.
