As it turns out, it’s Dennis Hwang, a 23-year-old Korean-American artist whose work has no doubt been seen by more people than, say, the Mona Lisa. Here’s an interview–it’s kind of banal:
Understandably, the “O” and the “L” are the easiest to deal with. The “O” has become a Halloween pumpkin, a Nobel Prize medal, the Korean flag symbol and the planet earth. The “L” has been used as a flagpole, the Olympic flame cauldron or a snow ski. The first “G” is the most difficult to deal with, and I don’t think the “E” has gotten much action because of its location.
