"Don't have an idea, have a moiré!" I've forgotten where this Ulmerism is written, it's just glued there in my head along with other aphorism-like statements – for example,
Mishima's "All style ages beginning with the adjectives, in short adjectives are flesh." I don't remember where I read that either, mnemonic devices can only do so much. In any case, in 1998 I made an image of the coolest velvet blue for this aphorism, this moiré
and later it became an important thinking point in the design for another website. The thoughts that generate a design often don't survive the alphabet. And I have learned to use plastic wrap sparingly.
Ulmer writes that the specific effect Derrida seeks in his writing is solicitation, which turns out to be the textual equivalent of the moiré effect.
Miriam Webster's Online Dictionary gives solicitation as "1: the practice or act or an instance of soliciting; especially: entreaty, importunity 2: a moving or drawing force : incitement, allurement
Incitement (a provocation) and allure as a moving or drawing force
a line for example, or the thread of a tune. Greg Ulmer reading Derrida writes, "Derrida wants to restore to writing the balance between design and symbol (between arbitrariness and motivation, chance and necessity) it had in hieroglyphics. His pursuit of the moiré effect, as an attempt to write the structurality of structure, contributes to this project by experimenting with ornamentation (abstract designs) as formulas or generative devices for text production
as part of his reversal and displacement of dialectical ideology, Derrida demonstrates the power of thought residing in "decorative" devices." These are matters for and of appearance: baroque folds and excess(es) of meaning
