Soap bubbles filled with smoke are used as floating, bodiless projection surfaces. They show common dreams and desires, which too often burst like bubbles.

For this first Prototype we invented a combination of a fog and bubble machine. A bellow creates the bubbles by blowing the smoke through a tube, which was moistened with soapy water before. To enable the cameratracking in the dark, the soap bubbles are illuminated with infrared and also filmed with an IR camera. The position, size and movement of each bubble is recognized in the visual programming toolkit vvvv. Finaly a short-distance beamer projects the images on the calculated positions.
