The interlace design motif remains popular in Celtic countries, above all Ireland where it is a national style signature. In recent decades, it had a re-revival in 1960s designs (for example, in the Biba logo) and has been used worldwide in tattoos and in various contexts and media in fantasy works with a quasi-Dark Ages setting. "The Secret of Kells" is an animated feature film of 2009 set during the creation of the Book of Kells which makes much use of Insular design.
