Acting
A transference of energy; an exothermic reaction. The marks are product. A way of distilling intangible energy into physical permanence. Skin is the carrier and the canvas.
Barriers are an augmentation not just a limit - they have potential for new sensations. Bodies take on different qualities. Smooth, shiny tactileness. Cold or warm when in contact with skin. Transmitting sensation without faithfully replicating it.
