Brick artist Nathan Sawaya is the autohr of this amazing anatomical heart:

“I created an anatomically correct human heart for the Rady Children’s Hospital of San Diego. A piece like this is a great tool to help doctors talk to young patients about their own hearts. Hopefully kids will relate to a heart built from a medium that they are familar with. It took me nearly 100 hours to create this heavy heart, weighing in at 35 pounds. The typical human heart weighs about 10 ounces, so this heart is a bit heavier. It also causes more heartache when dropped on one’s foot.”
