Harmonic Tower is a massive version of a Harmonograph. This popular Victorian device created small, mathematically patterned drawings (similar to those made by a modern spirograph) by means of pendulums. 

In Conrad's version, there is an added dimension of time, as rather than remaining still, the paper - located at the top of the tower - is drawn through the machine as the pendulums swing. The large-scale drawings produced by his device offer a visual interpretation of musical harmony, using a combination of rhythms and mathematical methods in their creation.
