Her ongoing monumental laser light installation
Global Rainbow has been presented over ten times since 2009 including: launching the
London 2012 Cultural Olympiad in the Northeast, It was also featured in Toronto, Ontario for Nuit Blanche in 2014. The
Global Rainbow installation beams seven rays of high specification laser light, representing the spectrum of the seven colors of the rainbow. The artist had been inspired by seeing an unusual rainbow in a "beautiful spot" at
Walden Pond in Massachusetts. Mattern aims to connect all demographics in a beautifully engaging experience. She sees her work as a visual translation of hope and peace. == Personal life ==
