We at Hybrid Elephant have quite a number of years' experience as graphic artists, including experience with traditional media, font and type design, publication design, camera work.
Among our work is Tengwar Sindarinwa (Grey or High Elvish), a cross-platform-compatible font designed after the Quenya, Sindarian and Fëanorian languages described in J.R.R. Tolkein's books The Hobbit, The Lord of The Rings, The Silmarillion, and many others. Please note that this font was originally developed in 1984-1985, long before the current popular movie-rendition of The Lord of The Rings was even being dreamed of.
The pictures above and below are illustrations of the Tengwar font in use. The top picture appears on the title page of the unfinished, and unpublished Sindarian Dictionary (below). This font was created before the Unicode standardisation for Tengwar had been decided upon, so the font's keyboard layout is as logical as possible, which means that on an American standard "QWERTY" keyboard, the Roman letters match up with the Tengwar letters whose sounds are similar when possible. Unfortunately this wasn't always possible (Quenya, Sindarian and Fëanorian sometimes use the same letter for different sounds, and they also contain some phonemes which are not represented by Roman letters for the English language), so the keyboard layout is a little odd, but learning to keyboard in Tengwar isn't really too difficult if you're familiar with the language you're using.
The Sindarian font is currently available for PCs and Macs, in bitmap, postscript type 1 and TrueType formats.
