Expression Intercession, a multi-media art installation, is a collaboration between artists David Lyons and Raz Ullah. The interactive environment consists of a wall-sized projected motion graphic and a dynamic soundscape. It was created as an artistic exploration of the processes of epigenetics through the support of EpiGeneSys, a European Network of Excellence based at the Institut Curie, Paris.

The expressions of the motion graphic and the soundscape are influenced by changes in the installation’s immediate environment. Those changes are triggered by audience interactions with sensors and projectors within the installation setting. The changes to the art resulting from environmental factors are meant as an artistic analogy for gene expression and changes in the epigenome.

Expression Intercession was exhibited in #Visions of Epigenetics at the the Cite des Arts gallery in Paris. Coordinated and curated by Paul Harrison, the gallery’s three floors featured artwork based around the theme of epigenetics. It was the artistic expression of a 3 year long scientific collaboration on epigenetics. The exhibition is documented in the book (re)visons. The exhibition inspired, and featured in, the French popular science magazine Biofutur’s art edition with Lyons and Ullah’s interactive environment contribution appearing on the cover.
