Shibulipi was invented when I was in Class VIII. It is a writing system for Indic languages, much in the same spirit as Nikhilipi or Bharathi Lipi. Based loosely on Bengali and Sanskrit writing systems, Shibulipi can be augmented and customized for any Indic language, including Tibetan and Thai.
Sample text in Shibulipi (Universal Declaration of Human Rights, Article I, in Bengali):
Bengali transcription: সমস্ত মানুষ স্বাধীনভাবে সমান মর্যাদা এবং অধিকার নিয়ে জন্মগ্রহণ করে। তাঁদের বিবেক এবং বুদ্ধি আছে; সুতরাং সকলেরই একে অপরের প্রতি ভ্রাতৃত্বসুলভ মনোভাব নিয়ে আচরণ করা উচিৎ।
I don't have a Shibulipi font yet, but if you are interested in designing one, please email me. Complete specification of Shibulipi is here, including background information. I reserve full copyright of the Shibulipi writing system. US Copyright Registration No: TXU001685803.
