Artwork by Luke Murphy
Luke Murphy, a New York based artist, uses anxiety as one of the central themes in exploring the fundamentals of randomness.
"Randomness is a great kind of source for anxiety because you don’t know what is going to happen. You can never anticipate it. A lot of my stuff has to do with anxiety, anxiety about anxiety. The anxiety about anxiety about anxiety is much more powerful motivator for people to act or not act than just the plain anxiety."
And one thing he has found that has the purest randomness happens to be radiation around which there is a great deal of anxiety among other things.
So over the years, he has created a body of computer graphic work that is inspired by radioactive substance.
One of them is called "Radiation Garden" which changes its appearance, however subtle, based on radiation counts collected through a Geiger counter set up outside of his apartment's window in Harlem. Looking at it, you know it is there, even though you don't feel it.
