Another interesting property of the logarithmic spiral is revealed if you roll it along a horizontal line. This animation shows the curves traced by points on the spiral, and note that the very centre follows the path of a straight line. The angle between this line and the horizontal is called the pitch of the spiral, and for our spiral galaxy the pitch is around 12 degrees. [more] [code]
Franco Casavola: Daniele Lombardi & Susanna Rigacci - Tankas 1 - 6 (2006)
1: En Regardant La Lune. 2: L’oreiller. 3: L’oubli Impossible. 4: L’inquietude. 5: L’attente. 6: Blancheurs.
When Marinetti wrote to Casavola in 1922, formally inviting him into the Futurist movement he mentioned already having heard the Tankas, so they pre-date, I assume, Casavola’s specifically Futurist pieces. Of course, the point was that his work was already perceived as obviously Futurist by existing Futurists which is why they wished to include him.
I assume - again - that the overall title is derived from the short-form non-rhyming Japanese poetry style.
geez, gifs are fun
