In this case the scenario is a shop with a variable identity. Each time a customer is detected by presence sensor the logotype will variate.
For this purpose I designed a specific variable font with Glyphs App which axe rotate 360º the glyphs.
To make each letter rotate randomly I use the JS expression:
return Math.floor(Math.random() * (max - min + 1) ) + min;
Here you can see the prototype working: Significant Function – random expression
