The #FreeBritney movement is feeling extra artistic after Britney Spears' impassioned testimony -- a massive art display, made of yarn, is echoing her call to end the conservatorship.
The artist behind the impressive yarn art, London Kaye, tells TMZ ... she used about 36,000 feet of yarn to create 5 iconic Britney looks and the "Free Britney" signage, and the whole thing stands 15-feet tall.
London hung the art outside the Britney Spears The Zone Museum in Los Angeles, it went up Wednesday and she says it will stay there for about 2 weeks.
London is an L.A.-based street artist who ya might recognize from "The Amazing Race," season 29. She says the Brit tribute recreates the singer's outfits from "...Baby One More Time," "Oops!...I Did It Again" and "Toxic" ... and took her about a week to make.
