I’ve finished. Cellspace 2 is based on a photograph I took in Natural Bridge State Park (Slade, KY). I thought it fitting, then, that the birds I included in the art resemble cardinals (two males and one female). As with everything in the piece, they are composed of high-resolution microscope images of blood vessel cells.
Qutub Lab (http://qutublab.rice.edu/) has given permission to use their beautiful cell images in this artwork. I do so with gratitude for their generosity and in awe of their research efforts.

The cardinal is exquisite, Nancy. Beautiful, beautiful work!
Thank you, Pam. I’m glad you like him; his feathers challenged me.
