Korean artist Soomi Park made these LED eyelashes to "speak to many Asian women's desire for bigger eyes." You can just use them to freak people out, per the video below.
Park's work explores the "increasing banalization of plastic surgery." Judging from her YouTube, it's only a matter of time before freaky body LEDs end up in Halloween costumes, horror movie wardrobes and, who knows, maybe in some sort of cosmetic body implant. People are talking these up as a Halloween costume, but Park's personal website is down, so you may be out of luck — this year.
