British YouTube channel TechMoan has an interesting beat: The host takes an in-depth look at unusual, vintage tech gadgets that did not survive evolution. It's fascinating for multiple reasons: One is to see what physical interfaces the designers came up with to handle previously unimaginable functions; two is to deduce why these objects failed, i.e. did they demand too much of the user or provide a service that no one asked for? Three is to revel in the vintage aesthetics; and four is to try to imagine what the designers were trying to achieve in the first place.

This first one is a Japanese gadget from the 1970s that you've never heard of, and which clearly bears the influence of Braun's 1960s and '70s design language. I won't spoil the surprise of what the thing actually does, but I will say that the designers were trying to provide users with a new sort of experience--and that the experience itself actually has persisted to the present day, only nowadays we typically gather within dedicated facilities, and get drunk together, to engage in it:

One thing I appreciate about all of these gadgets is the tactility, the need to manipulate physical metallic buttons and switches in order to get the objects to operate.
