Janet Based Periodic Table Layout by Ivan Antonowitz

"Every element has its own unique Periodic Table which is a mixture of two Ideal Forms. However, the main point at the moment is what level of complexity would be suitable? I am trying to get the most minimalistic presentation of the essential features. Explaining the logic governing the 'reversals' is quite tricky, if not controversial, and others may have more conventional rationales and so better fill in the details."
