Antrum is a graphical luminous interactive installation, created by Tatiana Plakhova. Artist describes her work as a grotto which the surface is inhabited by strange creatures. The aspect of it changes with the contact of touch from visitors, as if its came alive at this moment. An original way to make the public participate.

Its complex structure causes association with living creatures, space objects and architectural constructions. In this frontier world pure mathematical abstractions are mixed with natural shapes, resulting in formation of new entities. Viewers can push the membrane and try to contact with them.
