The paintings of 'Happy Birthday' are comprised of figurative studies that explore optic movement both within the paintings and changing perspectives of viewer interaction. Inspired by the famous example anamorphosis by Northern Renaissance painter Hans Holbein, double images are meshed into a singular painting displaying the interaction between two moments. Borrowing further from Holbein and other old masters, I have investigated their themes of mortality illustrated by traditional vanitas symbology through my own interpretation of the memento mori. Exploring notions of shared nostalgia and perspectives of my own family history, I have utilized optical effects that take advantage of the eye's persistence for continuous vision. The past is something shared and the present is fleeting, always changing. 'Happy Birthday' celebrates human transience through the inherently transient application of paint, construction and composition.
