VQC fags had fun with this early on.
In reality, math teacher Joey Grether originally developed the chart for his children. He tried to promote it via 12xspiral but with little success.
So he cheekily decided to create a hoax, making it look like the chart was by Nikola Tesla. [His post has since been taken down.].
There's an article about Joey (by Maria Droujkova) here: Exploring the spiral multiplication table, where you can see the original Grether's Spiral diagram.
