“Grand Spectrum” is a digital art by Richard Loskot and UAII studio presented at Signal Festival 2014 in Prague, Czech Republic.
Grand Spectrum is a monumental tribute to the natural phenomenon of the rainbow and its spectral effect. A circular projection system uses slowly moving artificial light sources to trigger overlapping spectra in a space where the visitors can enjoy the full variety of colours, from both outside and inside.
