What lighting effect is achieved by swinging a spot beam in a figure 8 pattern?

The lighting effect achieved by swinging a spot beam in a figure 8 pattern is commonly referred to as "Ballyhoo." This effect creates a dynamic and visually stimulating display that can be seen in various performance settings, particularly in theatrical productions or concerts. The movement of the light creates an engaging and lively atmosphere, capturing the audience's attention as the beam travels in a rhythmic, alternating fashion.

In contrast, the other options represent different lighting effects. "Blaze" typically refers to a more intense and broad lighting effect, often used to create a sense of urgency or excitement in a performance. "Flare" generally describes a sudden and sharp burst of light, which may not have the same fluidity as a figure 8 pattern. "Strobe" refers to rapid flashes of light which are used to create a dramatic impact, often associated with a sense of disorientation or heightened energy. Each of these effects can serve different purposes, but ballyhoo distinctly utilizes the swinging motion to create an animated display.
