IDEA BY HEXAGRAM
The Hexagram geometry makes it possible to think over
and imagine solid's shapes, distance and depth
which most people would feel difficult by
employing a 2-D shape of Hexagram. It's a epoch-making 3-D geometry.

DRAWING BY HEXAGRAPHICS　
By using the Hexagraphics,
you can easily draw a 3-D solid object on a plain
without any special technique or experience.
It comes from a space concept
of the Hexagram geometry and is a unique art of perspective.
