Grids of dots can be slightly morphed to resemble curves and slashes. Notice how some of the morphed versions of Dotsies appear visually similar to Asian scripts:

Interestingly, when you read Dotsies quickly and at a smaller font size, the scripted versions appear indistinguishable from the square (unmodified) versions. Because of this I didn't end up pursuing this aspect.
