I don't know if you knew that but there is this page http://sigilscribe.me/ where you write your will in a box and it translates it in a sigil, ready to be saved on png or vector format...I found it pretty useful because I kinda struggle to make nice sigils...anyway I thought it might be useful to you!
I dunno...automation sort of takes the fun out of creating something and removes the vital personal link to the finished product... Yet you'd still be envolved in the phrase structuring so the mind is still engaged in the outcome. Well, what the heck, if it's working for you, make it go!
Well darn. It only works for desk tops. I'm on an iPad but it instantly removed duplicates & vowels & reduced the remaining letters to a string of numbers. That's a time saver.
