Hello Andrey,

I’m sorry for being so late with plaudits for your latest amazing bit of
programming. I’ve only played with it for a short time but it is clearly
impressive. I especially want to join the other members who are
especially happy to see the 16, and especially the 24 cell. The 24 cell
is a truly special object on par with the monstrous 120 cell in that way
but is much more approachable than its photogenic cousin. I hope that
you implement macros before anyone solves these new puzzles. Or have you
already solved them?

Thank you for expanding our playground yet again,
-Melinda
