Sunstar (2018) was beamed across Pasadena in celebration of the United States’s Independence Day on 4th of July. The art installation at Mount Wilson Observatory (co-created by Lijn and the astrophysicist John Vallerga) is composed of prisms which take incoming sunlight and refract it, bending the light and spreading it into a spectrum – the colors of the rainbow.
Sunstar can only be seen in one place at a time. This happens when the software directs the refracted solar beam (rainbow) there. It is therefore a surprise for the majority of those who see it: an inexplicably bright and intensely coloured star in the daytime sky.
