This is an embalmed sheep's heart suspended in fluid, illuminated with a red light in the base.
This is a self portrait I took in my basement with aforementioned heart for a photography class.
This is an old phone embedded with carpet tacks.
Also, the full size homemade casket in my bar room, but I don't have any pictures here with me. I'll try to post one tomorrow.
