Buildering.

Buildering (also known as urban climbing, structuring, or stegophily) is the act of climbing on (usually) the outside of buildings and other artificial structures. The word "buildering" is a portmanteau combining the word "building" with the climbing term "bouldering".

Not something that I'd do but I like the video and editing.
