The concept of Duality has intrigued mankind since the beginning of civilization, and ancient Vedic texts propose several philosophies on the duality of nature in intriguing detail.

The artwork comprises of two objects constrained inside a 1cm³ box: a strip of paper with handdrawn phases of the Moon in glow-in-the-dark ink, and a nano-sim card that contains artistic simulations that are coded using Python programming language. Inspired by her Indian roots and Vedic influence, work is named “Bhedadipika – an illustration of Duality”. It plays upon several notions of Duality such as:

  • Constraint/Freedom
  • Light/Darkness
  • Minute/Infinite
  • Reality/Illusion
  • Randomness/Intent

The animated images are part of a series of algorithmic art titled “Star Cities/Organised Worlds”. These images are created by randomly generated points, but which are constrained to appear on a path defined by equations of epitrochoids and hypotrochoids of various parameters. An epitrochoid or hypotrochoid basically describes the path traced by a spirograph, and is one of the fundamental curves depicting movement in Nature: from celestial orbits to rolling objects. They instill a sense of harmony in the spectator, as the form is naturally pleasing to the eye. The artist imagines that if intelligent life were able to manipulate the formation of galaxies, it would exploit the humble hypotrochoid for inspiration for harmonious forms.

The ArtMoonMars initiative was setup to highlight the importance of artists with respect to space exploration: as message bearers who convey multiple messages of the community including planetary science, life sciences, astronomy, fundamental research, resources utilisation, human spaceflight, peaceful cooperation, economic development, inspiration, training & capacity building.

The Moon Gallery, by ArtMoonMars, is an international collaborative artwork and a gallery of ideas worth sending to the Moon. Moon Gallery intends to launch 100 artifacts to the Moon within the compact format of a 10 x 10 x 1 cm plate on a lunar lander exterior panelling as early as 2022. As it costs 1 million euros/kg to send something to the Moon, these (smart) artists proposed to hence miniaturise the gallery. The idea is to develop culture for a future interplanetary society in this Petri dish-like gallery.

The main team involves Anna Sitnikova (curator, exhibition designer), Elizaveta Glukhova (curator, graphic designer), Bernard Foing (space sector expert and visionary), and Alexander Zaklynsky (gallery founder).

Bhedadīpikā was selected as part of the Moon Gallery in 2019 and is a visual dialogue based on the artist's own duality - as an artist as well as researcher. For more information on the Moon Gallery Project, please visit their website. You can support the first mission to the ISS by donating here.

“Star Cities/Organised Worlds” was featured by the V-Art Digital #ArtSpaceship Exhibition (sector E).
