Paris, more thoughts on the Eiffel Tower

I've made my own re-take on a clichéd Eiffel Tower picture postcard, turning the image into my version of Foucault's Pendulum.

Foucault's pendulum is named after the French physicist Léon Foucault, who conceived the device as an experiment to demonstrate the rotation of the Earth. Foucault made his most famous pendulum when he suspended a 28 kg bob with a 67 meter long wire from the dome of the Panthéon in Paris. The plane of the pendulum's swing rotates clockwise 11° per hour, making a full circle in 32.7 hours.
