I very much like the Tartan Which Name Shall Not Be Spoken. If I had the discretionary funds, I would buy some yardage at least for a great kilt, if not a future X-kilt excursion.

At the very least, the tartan should be registered. I particularly like any name that is broad, because Hunting Cthulhu sounds risky, and Modern Cthulhu sounds like the description of an imitator of a famous dead person. Maybe, Cyclopean sett is appropriate.
