Getting There

It's working, only manually. I have to click for every piece. Getting there...

Finally got the code that produces unlimited scrambles on the puzz pieces.
Below, the two scripts. The randomizer runs 'onload', so that isfine. The second
code - the scrambler - starts with ordered pieces and scrambles them 'onclick'.
That needs to be looked at.

Had a bit of an epiphany about those return statements. Just like the rule on
functions is one function, one action; the rule on inputs and returns is one
input(s) one output. My first script works if I return y, which is then available
to run the second script. 😁
