Ventricle is a two-part installation created by SOFTlab that was commissioned by the Southbank Centre in London for the Festival of Love. The installations recall the heart, a symbol that has been used for many centuries and in many cultures to represent love. Along with the chambers of the heart, the installations are a modern interpretation of the hanging gardens of Babylon, a place of many cultures and languages, and also of Eden, a place of free knowledge and expression.
