LOJBAN, the logical language
Lojban is a synthetic language whose syntax is based on Boolean algebra (the mathematics of Logic).
Lojban also has a unique word construction system, such that one can speak a sentence running the words together, yet the ear can easily parse the sentence back into the original words.
Lojban forces completeness. The Lojban word for "make" literally means "x makes y using material z". Unless you fill in the words for x, y, and z you do not have a complete sentence.
The link below on using Tolkien's Tengwar alphabet to write Lojban amuses me, as I had the same idea years ago. They have developed it far better than I ever could, however.
Tengwar is a good match for Lojban, as the structure of the letters encodes the sound qualities. A stroke with a right hook on the top is "T". Closing the hook make the sound explosive: "P". A double right hook dulls it: "D".
