something's brewing

A deep hole at night, under a deep blue-indigo sky. The hole is viewed from the side through a cutaway perspective. The soil is gray, like concrete. The interior of the hole is rough and irregular. The end of the hole isn't visible, but whatever's down there is giving off an eerie radioactive green glow, illuminating the rocks on the side of the hole in sharp relief. Someone has placed a barbed wire fence around the hole, as well as a triangular warning sign. The painting is signed "Chris Silverman".
