[i]The project's precursor mission "Spiral Top", which was performed on April 30, 2009, was designed to produce light arts using a spinning top that has arms illuminating with LED point light sources. "Auroral Oval Spiral Top" was the second version and designed to produce aurora-like luminescence traces using a spinning top with both linear and point light sources. In microgravity, the center of gravity of the spinning top continuously and randomly moves while it is spinning. Using the characteristics of the top in microgravity, the project tries to produce various light arts using its unexpected movements/spins, by changing attaching locations of its arms and weights.[/i]
