The #RitzRainbow, a 25-mile laser light-beam art installation, was commissioned by Lionheart Capital to promote its Ritz-Carlton Residences, Miami Beach, development. Designed by artist Yvette Mattern, the installation originated from the company’s headquarters in the Design District. At a November 28 V.I.P. viewing, guests were escorted to the property’s private marina where they boarded Van Dutch yachts to watch the unveiling from Biscayne Bay. The #RitzRainbow was on display until December 3.
