Matthew Borgatti's awesome, intimidating Pillow Mace was created for an upcoming NYC Pillow Fight Flash Mob. He's promised an Instructable for those wishing to make their own: "Surprisingly it took a good yard of cushion foam and two bags of poly-fill to do this one up right and get it nice and spherical. In other interesting news this may be the first dodecahedron I've ever constructed."
