Kaleido v krychli... Kaleido in the cube ...

linda1802, additionally thank you for the wish for my birthday - I have found your comment only now. I'm sincerely sorry Ank is seriously ill. I'll be happy to write Ank to the link I got from you. Lenka

My very best wishes for a happy birthday, Lenka.

I think you already know, but allow me to remind you that sadly, Ank (puzzeljac) is not well enough to make a birthday puzzle for you this year. She recently completed chemotherapy and radiotherapy in a battle against an aggressive form of lung cancer and is still very weak. However, I'm pleased to report that she is slowly regaining strength.

To read what Ank wrote in her own words and the updates I have since added, I suggest you go to:

Again, my best wishes for your special day.
