Grandpa's art exhibit

My (recently deceased, in real life) grandfather is holding an exhibit of his art. His artwork thrills on many levels; it is smart, hip and humorous. His creativity and attention to detail are astounding. The crowd packed into the gallery is constantly erupting in delight as a new piece is revealed. One piece is a miniature tennis court made out of computer chips. One is a collage that incorporates multiple Guided By Voices references.
