Each piece is based on a classic videogame character as seen through the prism of real-life anatomy. They are rendered in clay, painted with acrylics and sealed in resin to give the appearance of a specimen preserved in formaldehyde. Seen here is a P. rotundus, which is based on Pac Man.
And just in case, from the Q/A:
Q: No photographs? What about a photo of a painting I did in real life?
A: A photograph of a sculpture, painting, or some other piece of art you have made are in fact exceptions to this rule. Feel free to submit scans and photographs of your art if it's not already in a digital format.
