Lay text out on a page as a Hilbert curve, so that words near each other in "time" (as if spoken) tend to be near each other in space (on the page).
Easiest is a grid of letters with lines or walls (like a maze) to guide the eye. Or maybe smoothly changing background colors.
More complicated is to create a new alphabet designed to be written in the highly twisty Hilbert curve. Morse code might be a good start. Electrical capacitor symbol. Thin line with large dot. Triangles of various colors pointing to the next letter. Thin line becoming thick, or double line.
Vaguely inspired by boustrophedonic writing sytems.
