Kazuaki

Kazuaki is a businessman in Kyoto, Japan. He produces very high quality mathematical puzzles. They're like jigsaw puzzles, but with more than one solution. They're made from extremely fine materials.

He can explain haiku.

FRAME GAME

These games are challenging.  He has more.

I admire his understanding of the axioms.

Jonathan

Jonathan composes very interesting pictures. I met him via email one day after locating his tutorial on how to draw a forest.

Dan

Dan is an author. He's developed a comprehensive (in my opinion) history of the Blackhawk Comics. And, he arranges for soldiers to sharpen their skills.
