The further out on a spike (away from the main mandelbrot) you stay, the simpler the pattern, less time it takes for your computer to do the calculations, and the easier for you to get a very deep zoom.
Same. I wish the convention was to call the usual "circle" puzzles something else, but we sadly don't have naming conventions in the twisty puzzle community to intuitively label and distinguish the two kinds of circles you can have on the faces.
Thanks. Looks like I'm up to 70 unique puzzles designs now including the 2 I just released. twistypuzzles.com/cgi-bin/pdb-search.cgi?&act=adv&inv=802&off=0
No, this version doesn't shapeshift, Though I may mess around with the design at some point to see if it would be feasible to add a few more cuts for an additional shape shifting variant.
Ya, the puzzle is a little bit stiff/sticky out of the box, though the turning improves quite a bit after adding some lube and taking time to break it in. I also tend to turn puzzles like this that shape shift a little slower as it can be a little tricky to see where the cuts line up. That said, the puzzle does feel very stable to where I'd have a difficult time forcefully taking a piece out without loosening up one of the screws.
