Yarn Bombing

We had errands near downtown Fort Worth the other day and stopped for coffee at Avoca. After that, we headed East on Magnolia Street to the shoe store and noticed a couple yarn bombs on the way. Next time I'm over there I'll take pictures to post, but here is an example from the Internet for now:

Example of a fairly elaborate yarn-bombed bicycle, with a link to more images, and a link to a how-to page, if you should feel the urge.

My companion had never seen anything like that before, and wondered what the deal was. 
"Yarn bomb! That's a yarn bomb!"
"What the...?"
"It's a creative expression, with sort of a guerrilla twist." I saw him looking sideways at me in disbelief. "No, really!" I asserted, "It's a real thing! Yarn Bombing!"
"Why in the world would someone DO that? and HOW do they do it?" 
"I don't know, but I've seen it before. It's pretty cool, don't you think?"

Yarnbombing! It's a thing!

Now he's worried about me going all lone-wolf yarn-bomby on him. No worries, though - I prefer more sedate, indoor projects for my yarn. It does look like fun, though, doesn't it?
