Kidney stone. Coloured scanning electron micrograph (SEM) of the surface of a kidney stone. Kidney stones are usually formed by the precipitation of the mineral salt calcium oxalate from the urine. The resulting hard, round stones (calculi) may cause severe pain, especially as they pass down the urinary tract. Large stones may need to be surgically removed or broken down using ultrasound therapy.

The design is of three arrowheads and one spear. The negative space of the each projectile point is in different shades of blue.

This illustration represents the process of lithic reduction, or knapping or flintknapping. Knapping is the process of creating tools by shaping stones, and it represented the height of human technology for tens of thousands of years!
