Here in the Western Hemisphere we tend to think of Indian saris in very traditional terms, so the idea of making one that incorporates high tech seems pretty alien. The Swaramadhuri Singing Silk Sari should dispel that notion, as it incorporates a 2GB MP3 player and eight microspeakers sewn into hidden pockets in the border. The sari was created by a designer in the Andhra-Pradesh region of south eastern India.
While saris don't generally come with a pocket for something as high tech as an MP3 player, I doubt that this is supposed to be some kind of boom box for the liberated Indian woman. It seems more likely that the idea is to play traditional music in a discreet way, creating a sort of aura around the wearer.
