This scene in the movie Harry Potter and the Order of the Phoenix takes place at Hogwarts when Professor Umbridge is coming out to remove Professor Trelawny from Hogwarts. The squares on the door are made up of right angles.
"'You didn't realize this was coming?' said a high girlish voice, sounding callously amused, and Harry, moving slightly to his right, saw that Trelawny's terrifying vision was nothing other than Professor Umbridge." -Harry Potter and the Order of the Phoenix, Page 595
