Just thinking about interactions and passing on or affects that occur through meetings. when A meets B, it changes A and B in some way. whether you learn a new skill, how to react or not to react, new information, triggers etc. Trying out some stuff with oil and water and then transparent glass paint and water. Glass paint in water makes a skin and then sticks to acetate paper. then lying it on white paper and shining a light through the back of it.
