Like our Logo, eSource Optics has always been facinated with the natural beauty of Rainbow's. eSource Optics Rainbowindow's state of the art Holographic Prism starts with laser technology and ends with pure spectral color. Hanging from a window in DIRECT SUNLIGHT, eSource Optics Rainbowindow will transform light into an explosion of multiple hues. Pinwheels of vibrant color will fan your room...splashing walls, ceilings and floors. Spokes of red, orange, yellow, green, blue, indigo, violet... and every shade in-between... will dance about the room, awash in a glorious spectrum of Rainbow color. The effect is absolutely spectacular!
