The pendulums are two stories tall. One ticks stalwartly in predictable harmonic motions like a Grandfathers Clock. Another; a weight on a wire, of almost exactly the same period, swings in chaotic orbits in all directions. A green laser monitors the chaotic swings. The two are connected at their pivots so that they tend to interact. In science, with all its certainties, chaos is always just around the corner. Strange Attractors is the name of the mathematics that deals with that interaction.The Trap and Strange Attractors together with WiS, were part three installations in one exhibition at the Darling Foundry in Montreal called Conflicting Realities.
