A new direction of art labelled 'land art' is the use of natural elements as inspiration and material for pieces. The artist Akira Inumaru uses flowers and dyes obtained from plants and subjects them to the effects of the sun. His work is also an experiment of how the sun creates colour, destroys matter, while simultaneously feeding the plants. The exhibit is separated into three parts Iki-utsushi (Double) and Ignis fatuus ( Jack-o’-Lantern) using flowers and plants as the main medium, and the third titled L’arc-en-ciel des plantes (Rainbow of Plants), consisting of work from plants that are a natural source of dyes. The colours obtained from them resulting in the seven colours of the rainbow. The exhibition is part of a series of presentations by artists from the MOCAK Collection. After the Logical Emotion of 2015, it is also another exhibition showing the achievements of contemporary Japanese artists.
