Tatlin achieved fame as the architect who designed the huge Monument to the Third International, also known as Tatlin’s Tower. Planned in 1920, the monument, was to be a tall tower in iron, glass and steel which would have dwarfed the Eiffel Tower in Paris (the Monument to the Third International was a third taller at 1,300 feet high). Inside the iron-and-steel structure of twin spirals, the design envisaged three building blocks, covered with glass windows, which would rotate at different speeds (the first one, a cube, once a year; the second one, a pyramid, once a month; the third one, a cylinder, once a day). High prices prevented Tatlin from executing the plan, and no building such as this was erected in his day.
The picture is a model of what would have been an amazing structure. Maybe someday someone will build it.
Here is a short animated video by David Cox while as a student at Swineburne University in 1990. It is very creative and seems to fit with the picture above.
