I'm finding the eight scripts (actually seven, one used for two languages) posted this past Sunday (2010-03-22) endlessly fascinating. The inventor, Prasanna Sree of the English department at Andhra University, has combined elements from various sources for each of the scripts.
In general, they are sort of grab-bag combinations of elements she invented herself plus letters from a variety of Indian scripts, either on their own or combined with other shapes into a single letter. Sometimes the borrowed letters are used for the sound in the original script; as often if not more, she just assigns them arbitrarily to a different sound in the new script. Apart from letters or parts of letters from Gujarati, Devanagari, Sinhalese, Tamil, Bengali, Burmese and possibly Malayalam scripts, she also uses a couple of hiragana, at least one letter from the extinct Bimanese script of Sumbawa as illustrated by Raffles, at least one letter from Georgian, quite likely the Inuktitut ‹vu› and several from Old Philippine Baybayin.
Her invented scripts are interesting, though I wonder why she went to such lengths to get all these letter shapes from all over the place only to use them in such an arbitrary way...? And the letters in several of the scripts seem too complex by half to be really practical, though that may just be my personal impression...
I'm wondering if anyone else can detect letters she might have taken from other scripts and used either with their own values or just used arbitrarily for another sound?
