The Continuum collection are pieces exploring the relationship of moments and quiet time with the Symmetree Oak. Each is an impression of memories spent studying the oak tree during the 3 years that Mark documented it.

He uses an original technique that he developed, slowly building fine layers of resin, leaf, painting and print to combine both print, mixed media in resin.

Many of the Symmetree pieces are created from a number of photographs. Mark would typically walk around the oak tree taking up to 12 photographs, which he often combines in the final pieces.
