We recently created this sugar skull for a client.  Initially carved out of polystyrene, it was then reinforced with fibreglass so that a performer or dancer could climb in and out of it, while being wheeled around the dance floor.  The skull was beautifully hand finished in traditional sugar skull designs with the additional wow factor of also being painted in UV reactive paints so that as the main lights get dimmed, the designs on skull would start to shine out.
