A design that looks like a top-down view of ziggurats!
I composited the diacritics so they'd fit into place, but this means that most anything non-English needs to be pretty large to be unambiguously read...
This font was made to resemble the Mara glyphs seen in the queue of Indiana Jones and the Temple of the Forbidden Eye at Disneyland, CA.
It looks like a different language, but each glyph very loosely resembles a letter in the Roman alphabet, allowing the text in the queue to be "translated."
The Zephiest of designs - a gaggle of Roman columns with gongs stacked on them.
A single line is bent on itself to trace letterforms in 5x5.
This is part of my "IVO" series (Inline Versus Outline) wherein inline and outline elements are split, merged, and altered to make them ambiguous and to allow new styles to emerge. They may look like maze fonts, but they have a different design methodology altogether.
I finally made a folded-/ribbon-style design. This one contains a number of experimental techniques. Most notably, the swept parts of glyphs are allowed to extend beyond the letterwidths and sometimes even the baselines. This enhances the sense of movement, creates some interesting linkages, and reduces the need for kerning.
All of these shapes can be constructed with paper or ribbon, although lots of clever folding tricks, doubling, and pinning down/securing with glue would be required.
Alternate tilde on "±".
