Marc's kaleidoscopes are very innovative and imaginative. He is respected as one of the top designers in the kaleidoscope community. Marc seems to enjoy the unusual mirror system configuration. He hand paints glass for the exteriors of his kaleidoscopes. Then he reverses the glass so the painting is on the inside of the glass. This exterior technique creates very rich and textural colors in Marc's work. His mirror systems are the most creative concepts and seem to defy the imagination.
