Techesoterica is a blog dealing with sensory substitution and other esoteric technical concepts. My name is Pranav Lal, and I started using computers in 1991 and began by deleting command.com in DOS. I am a self-taught programmer and continue to program as a hobby. I work with all things technology and enjoy tinkering. Other hobbies include travel, reading (at least 1 novel per week) as well as writing shortstories and photography.
