We will create a physical box that uses temporal aliasing to make ordinary objects appear as though they are dancing to music. The project is primarily motivated by the KickStarter campaign [Slow Dance – A Frame that Slows Down Time](https://www.kickstarter.com/projects/xercyn/slow-dance-a-frame-that-slows-down-time), with the added goal to time the resulting movement to the rhythm of any song. The banner image and diagram below show the original model upon which our project is based.  The box creates the illusion of slow-motion dancing by vibrating an object at a high frequency and timing a strobe light at a near frequency. The interference pattern produced by the vibration and strobe light’s frequencies causes the vibration to appear significantly slower. As explained by the persistence of vision, the human eye perceives the discrete positions upon which the strobe illuminates as a smooth, natural motion. Peculiar motions of the object are visible since the actual high frequency vibration causes the object to move in an irregular fashion. The beat frequency of the resulting motion is determined simply by the absolute difference of the two input frequencies. We intend to attach an audio input and speakers to our box. From the audio we will automatically detect the beat of the selected music, and determine the vibration and strobe frequency such that the object moves at the same beat. Alignment of the interference and music phase shifts (such that the apex of an object’s motion aligns precisely with the music’s downbeat) will initially be manually calibrated, and if necessary, may be determined via an additional calibrating sensor. Code for our project can be found in our [github repo](https://github.com/suhaasr/build18-s17).
