Pictographic sigils have become my favorite way to work. Just let the image come to you based on the feeling of the word. ‘Mercy’ turned into two figures holding hands under a sunrise. ‘Work’ became an ox head.
So much more alive than any letter-scrambling, and I think it’s because you’re tapping into something the conscious mind isn’t filtering first (which is kind of the whole point). I still develop a short punchy activation phrase to go with each one, but the single-word visual is where the real magic lives.
