Wow. This is pretty amazing…
“Ink Calendar” make use the timed pace of the ink spreading on the paper to indicate time. The ink is absorbed slowly, and the numbers in the calendar are “printed” daily. One a day, they are filled with ink until the end of the month. A calendar self-updated, which enhances the perception of time passing and not only signaling it.

“New York architect Edwin Koch had a brainstorm in 1939 — he proposed a teardrop-shaped “hurricane house” that could rotate like a weather vane. “This amazing dwelling would revolve automatically to face into the oncoming storm, meeting it like the wing of an airplane and passing it smoothly around its curving sides toward its pointed tip,” explained Popular Science.”
Idea from Edwin Koch, text from Futility Closet.

As Fowler and his colleagues examined the various types of bite mark on the skulls, they were intrigued by the extensive puncture and pull marks on the neck frills on some of the specimens. At first, this seemed to make no sense. “The frill would have been mostly bone and keratin,” says Fowler. “Not much to eat there.” The pulling action and the presence of deep parallel grooves led the team to realise that these marks were probably not indicative of actual eating, but repositioning of the prey. The scientists suggest that the frills were in the way of Tyrannosaurus as it was trying to get at the nutrient-rich neck muscles.
