McCann has worked and exhibited in the fine arts field for 30 years. His work uses a variety of materials tailored to the intent and content of the art. Being self-taught, he began in the early 70s working with glass, designing and building stained glass windows and fused glass, and creating a line of fused glass jewelry.
The move into mixed media began in the early 90s when he felt his glass work began to stagnate. He started using arbitrary objects to create order with a visual impact, establishing a relationship with the objects Arbitrary Order.
