Here's a dress made out of 436 white circuit boards, all tied together with metal rings. Each one of the boards is addressable from a control unit hidden in the back. All of the circuits are powered with solar cells, and there's even an RF receiver that can download commands from afar.
Each one of the tiles can have a solar cell and an RGB LED embedded, so various lighting patterns can be displayed on the dress. You light up my life, baby—let me stand next to your fire.
