Finally, I completed a page on my wall painting. It depicts projections of the four Platonic solids in two dimensions.
The link to the page: https://www.ceesjansen.nl/en/plato-in-flatland/

Metaphysics page updated
The page on metaphysics has been updated.
I added some text on numerology. It concerns a result obtained by myself earlier this year. Three-digit numbers, divisible by the sum of their digits, placed on the four sides of a pyramid. This shows the three dimensional generalization of the Tetractys, Pythagoras’holy symbol.
More to come.

Projects with the purpose to replace the encryption technology, usually DES, in equipment like Nokia Sanla and Parsa, MEL’s EMU-Alpha and The FM8600 Fequency hopping Combat Net Radio of Hollandse Signaal with readable encryption.
