So here's my plan for April 15: I make a large bird/butterfly winged creature with a 6 ft wingspan out of a bedsheet. and flutter it across the intersections around Worcester MA City Hall and Town Commons. Not stopping traffic but making liberal use of the crosswalks.
I will paint an #XR hourglass symbol on the sheet, laying on it's side, so each end of the hourglass forms the butterfly/bird wing, painted in brilliant colors.
