The Surrealism of Everyday life

Found out from BoingBoing today (my favorite alternative news source) a woman at an art gallery came face to muscle (?) with her own heart. She'd had a heart transplant and donated her former, now it's part of an educational art exhibit.

This leaves me pondering the surrealism of everyday life.

This link to mortality, this representation of life and love and humanity, sitting in a box as part of an art exhibit. What makes biology art. Is it enough that an art piece make people think, or must it be more to be classified as art? If it must be more then what makes a useless (diseased) muscle art? If all that is required of art is that it make people think, what is the difference between art and education?

Is a heart in a box a biology class, or an art exhibit?
