Blood on a bandage.

 I was doing some work on my car. I got cut, after I cleaned it up and put a bandage on it. I wondered what my blood would look like under a foldscope and here we have it. 

Poinsettia

These photos are of a red leaf taken from a Poinsettia plant. The pictures are of different veins in the same leaf. The red photo was backlit by an incandescent lightbulb, while the purple photo was backlit by an LED.
