You will need the following:
a mechanism capable of rapidly moving a light source through space. This can your hands, as guided by a rail, or it can be made from an old X-Y plotter, or using more modern drive mechanisms such as stepper motors or the like;
a light source such as a light bulb or LED, or an array of light sources such as a linear array of computer-addressable lights (SWIM);
a phenomenon amplifier as described in a previous Instructable.
It also helps to have a dark environment, e.g. a room with subdued lighting, so you can see (or photograph) the phenomenological augmented reality more readily.
