Here is a suggestion about clock scramble notation. The actual notation has an important limitation : it relies on some text display or some ascii art to be able to understand it. The problem with this is that it cannot be manipulated (changing the font, the size), it is very difficult to be parsed, so to be saved, translated into something else, etc. It is very different from the scrambler notation of all the other puzzles.
Also, minor issue, when scrambling on a computer, text is very small if you want to fit the whole page on screen.
So I propose to use a more standard notation for clock, and add a section in the regulations with how to interpret the scrambles (which is missing right now). Coming from square-1, I propose something like this :
(UUdd,1,-2) (dUdU,3,5) (ddUU,-2,4) etc.
First pins position, then turns around U pins and turns around d pins. I'm not stuck on this particular notation, everything that can stand as a text sequence with no line break is fine for me.
What do you think ?
