Jason Freeney hand-sculpted this 7.5" tall Lego Man, who is showing it all. It all, of course, being his interior anatomy.
I like the sculpture a lot, but I think Freeney is wrong about the feet and hands - Lego Men have no fingers or toes. Come on, Freeney, get with the program!
See more of Jason Freeney's art at his blog. He has a whole series of anatomical sculptures.
