Finding new ways to get in trouble, and get a message out. Katsu is tagging up walls faster than ever and in new ways. Bet you haven't seen this.

I have never tagged a building in my life. I actually don't condone what these guys do. It is illegal. But with new technology and a little know how taggers have gone high tech. So if you ever wondered how someone got their name or tag 30 feet tall on an overpass, now you know.

Using a fire extinguisher to paint. This is the first I have seen of this idea. Perhaps the practice can be turned into something useful in the future. I have also seen them using flying drones for tagging, but so far nothing readable.
