Triangle Twirling

I had hoped that alternating concave and convex blocks of  the curved triangles (like this, above) would create the movement I wanted.

Alas, they did not. While this is moderately pleasing, it isn't exciting enough to float my boat. As my pal the Selvage Fairy said to me once, "It's interesting you think the worst [your design] could possibly be is nice."

But it was the Selvage Fairy who set me on this path of curves in triangles in the first place. She wanted to know what would happen with these blocks if I rearranged them. Dear Selvage Fairy, your request is my command...

So I started tinkering, but this did not float my boat either. This was boring boring boring. Too much been there done that.

However, there was one shape in this photo that I DID like very much.

THIS ONE! I thought THIS had distinct possibilities, so I moved the pieces around again...

By the time I was halfway down, I knew this was THE ONE!

I still have to rearrange the blocks to distribute the colors and patterns a bit better, and I need another vertical column over on the left to complete those dark shapes over there, but this overall layout is it.

I love the optical illusions it creates, the movement, and the sheer unexpectedness of it.

For those of you wondering how it works, this should explain it.
