I had already done this for a few of the numbers in my number-association system such as 0 as an egg, more specifically Humpty Dumpty from the nursery rhyme. 00 is Dorothy from The Wizard of Oz because that story was written in 1900, but also 00 looks like an overhead view of a pair of ruby slippers, and furthermore Dorothy has two Os in her name like 00. 01 is Gandalf from “The Fellowship of the Ring” which (film) came out in 2001, but also I think of it as being one (1) ring (0) so it’s 01.
For most of the rest of my number assignments I haven’t yet made such associations to the actual shape of the numbers, but I’m going to be on a greater lookout for this for sure! It’s nice when you get some extra associations for numbers that just so happen to fit, for example in my system I have 747 as a Jumbo Jet, because that’s immediately what I think about when I hear the number 747 (Boeing model). But in the Josh system that number is pronounced “cock”, just like cockpit! (I guess they call it a flight deck now to be more politically correct). But now when looking at the shape of the number I realize there’s another connection: the 4 is like the body of the Jumbo Jet with its distinctive hump at the front, and the 7s are like wings on either side
