The Centaurs was an animated film produced by Winsor McCay between 1918 and 1921. There is no record that the film was completed or publicly screened. The film was destroyed by negligent storage that allowed the sole surviving nitrate film print to deteriorate into dust. All that remains are isolated fragments that total approximately 90 seconds.

Solar eclipse of January 4, 2011. This is a movie made by the space telescope SWAP: Sun Watcher using APS detectors and image processing. The movie shows the Sun in extreme-ultraviolet (EUV)-light. The solar disk is partially blocked by the moon.

Near the café Kraantje Lek in Overveen people train their muscles and form for the coming ski season. There's also a fashion show of ski clothing for women by fashion house Leeser, a.o. several coats, a.o. with striped design, icicle design and divisible hood, an elastic trousers, evening wear and a mohair skirt. (November 1959)

High-speed digital sequence of a vertical impact by a copper sphere traveling at 4.5 km/sec into porous pumice (density of about 1g/cc). A side-view of a near-vertical impact at 500 frames per second (or 2 milliseconds between each frame) taken with a high-speed video. This is a 60-degree impact (from horizontal) into a highly porous target of fine particles. Now you can see the funnel-shaped ejecta curtain moving across the surface after the crater forms. The curtain resembles an inclined wall of particles that actually represent the collection of particles ejected at a well-defined position, time, and velocity. Eventually the crater emerges from behind the ejecta curtain as it moves outward and becomes transparent. This sequence illustrates the evolution of a crater that is stopped by the effects of gravity, rather than strength in the target. These ejecta are launched out of the target and only gravity limits how far they can travel beyond the rim on ballistic trajectories. If the target had strength, the curtain would seem to separate from the rim as the crater finishes.

"It's a Long Way to Tipperary" is a British music hall and marching song written by Jack Judge that, allegedly, was written for a 5 shilling bet in Stalybridge, on 30 January 1912 and performed the next night at the local music hall.
