The works of Jana can be added to the field of biomorph plastics. He makes his sculptures to metaphors for the act of creation similar to nature. He unites the plastic from with the growth of nature. He explores thereby the whole evolutionary hierarchy of the minerals, Flora, Fauna up to humans, in order to show that nohierarchy exists and the same forces are working through all. Janas early works are stressed by the principle of coincidence, according to which the forms swim against each other.
