The Belvar alphabet was invented by DonZabu from March 2010 to May 2010. He got the idea for it during a brief immersion into the Lojban community, where he found that there was some demand for a writing system that kept to the same principles that Lojban itself was founded on: logic, unambiguity, and cultural neutrality.
Functionally, it's based on the International Phonetic Alphabet. Visually, it's based on the Latin alphabet, with the individual shapes chosen more for their morphability than anything.
Each Belvar letter conveys 3 pieces of information: for consonants, it's the place of articulation, the manner of articulation, and whether or not it's modally voiced. For vowels, it's how open it is, how front-to-back it is, and whether or not it's rounded. The consonant letters convey this by shape, stem, and underline respectively, and the vowel letters convey this by shape, diacritic, and underline respectively.
I give this script a 4/10.
That's a 3 for functionality. It does however lack distinguished characters for non-pulmonic consonants, affricates and co-articulated/complex consonants, this means it falls short of its creators claims of being able to write any language. It does come close to providing a kitchen sink for phonemes, but that does not necessarily make it a complete script.
A 1 aesthetically. I am tempted to scream Tengwar, but that would be trite an memetic. It is my experience that very few people enjoy a script that has a multitude of repetitive symbols simply flipped horizontally and/or vertically. I do not think this script comes anywhere near aesthetically pleasing, at least not in its current state. I think it would be nice if the author would attempt some cursive or free writing and see where this script goes.
