Mechanical flip board. Technology of the past but somehow so cool.

The proper name for these is split-flap displays and I'd totally buy one and set it up to show the number of users on the fediverse.

@benoit the one in gare du nord was so cool, kinda gutted SNCF Gares & Connexions replaced it with a big ad screen...

@benoit I still remember raster graphic displays at train stations, where each pixel was like a little book. The middle (book pagees) was painted fluorescent yellow, the outside (book cover) was black. Flipping the book open and closed permitted to display arbitrary pattern, although at a low resolution. Sorry, can't seem to find a video.
