Dazzle camouflage

Dazzle camouflage

Interesting article over on TwistedSifter about the use of so-called “dazzle” or “razzle-dazzle” camouflage beginning during WWI. (The Wikipedia article is pretty good, too.) It’s a kind of practical op-art: The idea was not so much to make the ship invisible against the background, but to confuse enemy weapons operators as to its distance and heading. The Rhode Island School of Design has a wonderful online collection of various paper plans for dazzle camouflage schemes donated by Maurice L. Freedman, who was district camoufleur for the 4th district of the U.S. Shipping Board, Emergency Fleet Corporation, and would go on to invent the board game “Battleship.”

Paper model of expanding 6-bar Bricard linkage

YouTuber 36AM3B has lots of cool deployable-structure models in his channel, including an expanding frame (visible to the rear in this video) made from 5 of these 6-bar linkages. I got interested in Bricard linkages because of this recent model from Thingiverse user raju, which purports also to be a 6-bar Bricard linkage but looks, to me, an awful like what I’ve always called a kaleidocycle or flexahedron.
