Hi, is it possible to associate a formula to the “rand” and “wakeRand” expression to make letters appear randomly (instead of numbers)?

I was thinking about a conditional expression like: “If random number is N, then show L” on a list associating numbers N between 1 and 26 to the corresponding position of latin leters from A to Z. But I don’t even know if this is possible on Facer.

There goes some committment on math and logic here and I think I lack the skills to do that.

Sure you can
Use
Text layer “A” transparency $(wakeRand(1,26))==1?100:0$
Text layer “B” transparency $(wakeRand(1,26))==2?100:0$
Text layer “C” transparency $(wakeRand(1,26))==3?100:0$
