I came across this today, and thought others might appreciate a look as well.
The Chinese artist's name is Zheng Chunhui, and the piece is 40 feet long, carved from a single tree. It took 4 years to complete, and won a place in the Guiness Book of World Records for it's length. (The quality of the work isn't too shabby, either.)
Also:
The record for most darts caught by one hand in one minute and most upright bottles walked across were, oddly, broken at the same time and by the same person.

(You need to see the other pics to fully appreciate it.)

Hats off to this guy's patience, I reckon.
