elvish: n.

1. The Tengwar of Feanor, a table of letterforms resembling the beautiful Celtic half-uncial hand of the Book of Kells. Invented and described by J. R. R. Tolkien in The Lord of The Rings as an orthography for his fictional ‘elvish’ languages, this system (which is both visually and phonetically elegant) has long fascinated hackers (who tend to be intrigued by artificial languages in general). It is traditional for graphics printers, plotters, window systems, and the like to support a Feanorian typeface as one of their demo items. See also elder days.

2. By extension, any odd or unreadable typeface produced by a graphics device.

3. The typeface mundanely called ‘Böcklin’, an art-Noveau display font.
