The grooves engraved in the two rotating boards are called "logarithmic spirals." These two grooves always cross at right angles, and a square hole is formed at their intersection. The goal of this puzzle is to remove the helix ring that goes through that hole. The inspiration of this puzzle is the morning glory. The puzzle was designed to look like a bud that comes into bloom with twining tendrils. The original concept dates back to 1990, but it has been enhanced with the addition of several tricky features. The theme of this puzzle is "Flower."

Designed by: Akio Yamamoto 2009

This is one of my favourites! I had to observe it very well before I found some interesting part of it and then I tried to use it. And it worked! The cast is beautiful, too.

Took 2 hours to figure out the intended solve. You can brute force it, but the intended solve is actually very clever and oh so much more gratifying.

This puzzle is unique and has a lot of personality, it is one of my favorites, but I haven't gotten it apart yet. I just like looking at it, and playing with it is fun.

Little bit of forcing in the end.

I must admit I'm a bit disappointed in this puzzle. After a half hour I got the ring off but my a little bit of force. I have now taken the ring on and off several times in two different ways and I think none of them are the intended solution, because they are rather easy and seem to use a little force at one point. Please add the solution to this puzzle as I am quite baffled at what the "correct" solution is.
