*The birth of the Paperclip.*
This is very useful to me. I found the modest paperclip to be very inspirational as an example of a 1 dimensional object, shaped into 2 dimensions, that’s designed to control 3 dimensions. Of course it’s 3 dimensional (well, 4 or 5 dimensional depending on how you want to look at it) the whole time.
From a 4D point of view, this is its birth-time.
