Japanese designer Kouichi Okamoto’s “bookmark light” is every reader’s dream gadget!
This typical looking bookmark transforms into a light source in a blink! Using materials like silver nano particle ink, LED chip and lithium coin battery Kouichi Okamoto has developed a circuit for 'bookmark light' that is printed on a special film using ink, which transmits electricity; making it a bookmark and an illumination source using a lithium coin battery.
