Tennessee artist Herb Williams has been commissioned to construct 3-D flames out of 60,000 to 70,000 Crayola crayons that melt and warp under the raging Texas sun. Blazes have become a very serious threat in Texas this year, as the state endures its worst drought in history. Unwanted Visitor: Portrait of Wildfire opened October 7 to educate the public about the rising issues of wildfires.
