Optical Poem, an abstract piece of stop-motion history, was made in 1938 by German-born Oskar Fischinger, an avant-garde animator, filmmaker and painter. The familiar music is Franz Liszt’s Hungarian Rhapsody No. 2.

A modern audience may be unimpressed by such sights in an age of endless computer-generated, digital imagery; this film is a hand-crafted, analog mood piece that takes the viewer along on an abstract journey that can inspire any number of interpretations. In his book Optical Poetry: The Life and Work of Oskar Fischinger, William Moritz takes a stab at it, writing that “the keen sensation of depth becomes a conceptual part of the action, with the circles that rotate around each other revealed as cosmic figures that could be either microscopic cells or stellar configurations.”…

This sort of stop-motion animation work is slow enough, but consider that Fischinger was not moving rigid metal model joints, but lightweight pieces suspended by thin lines and thus prone to sway he had to make sure each piece was steady before making his exposure. The artist used a broomstick with a feather attached at the end as a “steadier.” Moritz further pointed out that “as in most of Oskar’s films, complex choreography often required a dozen figures to move simultaneously, some in the same direction, but others at a different angle or direction, so each exposure was slow and had to be carefully monitored.” The phrase “carefully monitored” is quite an understatement a miscalculation could ruin a shot and lead to the scrapping of many hours of work.

From the team that brought us The Secret Life of Plankton and The Plankton Chronicles comes this wonderful TEDEd video from their amazing microscopic footage, re-created to explain How Life Begins in the Deep Ocean:

Where do squid, jellyfish and other sea creatures begin life? The story of a sea urchin reveals a stunningly beautiful saga of fertilization, development and growth in the ocean depths.

After watching The Secret Life of Plankton, oh how happy we were(!) to find Para Films‘  The Plankton Chronicles. There are so many beautiful videos shot in microscopic detail that we haven’t watched them all yet.

In this video, the Sea Urchin and its cone-shaped echinopluteus larvae demonstrate the cell-division cycle. Other excellent vids: Protists - Cells in the Sea, Iridescent CtenophoresPelagia - Fearsome Jellyfish, and Pteropods - Swimming Mollusks. Stunning film work and really breathtaking science. 

The circulatory system consisting of the heart, arteries, capillaries, and veins, is the pumping mechanism that transports blood throughout the body. In the heart, the left ventricle contracts, pushing red blood cells into the aorta, the body’s largest artery. From here, blood moves through a series of increasingly smaller arteries, until it reaches a capillary, the junction between arteries and veins. Here oxygen molecules detach from the red blood cells and slip across the capillary wall into body tissue. 

Now de-oxygenated, blood begins its return to the heart. It passes through increasingly larger veins to eventually reach the right atrium. It enters the right ventricle, which pumps it through the pulmonary arteries into the lungs, to pick up more oxygen. Oxygenated, blood reenters the left atrium, moves into the left ventricle, and the blood’s journey begins again.

Nothing like riding through the body to get the point across!
