Pillars of Creation is a photograph taken by the Hubble Space Telescope of elephant trunks of interstellar gas and dust in the Eagle Nebula, some 6,500-7,000 light years from Earth. Pillars are considered to be a cradle of stars, but UV emission from newborn ones inside the pillars' cores tears them apart, so they are also a Pillars Of Destruction.
That kind of object inspired me to make an invisible UV mural on SilkPlaster wallpaper at my place, when I discovered AcidColors Phantom UV invisible paint.
This paint allows to switch between environment atmosheres by a turn of switch.
