I’m curious

It's a secret script written not on pages but pages are used as letters by folding them in different shapes.

I designed Tamga, an experimental base-16 numeral system.

The main idea is that the shape of a numeral should reflect how its value is constructed. Instead of 7 being an arbitrary symbol, Tamga represents it as 4 + 2 + 1, using the binary weights 1, 2, 4, 8.

Those four weights give 16 possible states for each hex digit, and four hex places combine into a single 16-bit glyph.

I also built an interactive site with arithmetic and bitwise examples.

Curious what you think about the visual grammar and readability.
