A surefire way to make any given thing cooler is to use lasers. This definitely applies to rainbows. Sure you can make yourself a rainbow by aiming a beam of light through a prism, but how about taking 7 lasers of appropriate color and firing them off into the night sky? It definitely seems like an upgrade. Yvette Mattern is doing just that with her light installation Global Rainbow, now blasting across the UK, lighting up the North Tyneside coast for the first time last night. The purpose of it is to “encompass geographical and social diversity in its reach and symbolise hope,” but presumably to just look awesome as well.
