The Forgotten Kaleidoscope Craze in Victorian England | Atlas Obscura
A wonderful investigation of a culture-shifting mobile device: the kaleidoscope. A classic Gibsonian example of the street finding its own uses for technology, this story comes complete with moral panics about the effects of augmenting reality with handheld devices.
(I’m assuming the title wasn’t written by the author—this piece deals almost exclusively with pre-Victorian England.)
