Depending on the surface on which the artwork is painted; the artwork can be painted directly on the surface or on a medium that is easily removed after the event or the need for the painting is over.
*The 3D effect/illusion of the painting is experienced only by looking at it from a single spot and through a lens (mobile phone camera, camera, single lens, video camera) *After the painting is done I will mark that position for visitors *While painting, the content is adjusted to the current conditions on the surface and areas that can be painted: e.g. manholes, gutters, large cracks in the surface, etc.
