The real-time computer simulation driving SUNLIGHT mixes scientific imaging with how our eyes perceive the sun. The projected sun shrinks in size as it rises up the building and changes from red to orange to yellow to white. Sunrays increasingly emanate from the projection as it reaches the top of the building. The ‘omega’ and the green flash phenomenon, difficult to see with the naked eye, are shown accurately in the projection. SUNLIGHT provides the unique experience of examining the sun first hand.
