David Poppie creates some extraordinary works of art with sliced pencil crayons. So many layers and gradients of vibrant hues. As someone who pulled apart many pencil crayons as a child to see what was going on inside, I am dazzled by these complex pieces. It goes to show that any material, even one from your childhood art box, can be used in a beautifully modern way. If you happen to be in New York, you see more sliced pencil wonders at David’s “Ebb & Flow” show opening in September at Pavel Zoubok Gallery.
