I love building things.  I started building a house out of matches.

What is he known for?
1_Wizard
Well, many of his pieces are temporary and constructed in public places. He is what I refer to as an opportunistic artist
0_Apprentice
Interesting!  Did he get permission to do these pieces, or was it on a whim?
1_Wizard
Mostly on a whim. For example, one of his most influencial was called 'Polaris' which is a replica of a submarine to protest the nuclear arms race

So, he was political?  Did the pieces accomplish his goal?
1_Wizard
Yup. At one point a person took offense to one of his public art pieces and tried to burn it. It didn't work and he got burned instead. Fatally.

What!  He was killed by being burned alive?  Did they catch the assailant?
