During 2015, the International Year of Light, a traveling exhibition was developed and dedicated to holography. Despite the holograms are present in our day life, through several formats and different applications, for general public these 3D images are strange elements from complex technology. This exhibition explores several contents related with holograms, such as history, techniques, equipments, setups and applications and it involves a main structure with six interactive exhibits and a lab for hologram recording. The exhibition includes a group of nine art holograms, a workshop table dedicated to scratch holograms and a touch screen with information about holography, which can be download on-site or at home. All these contents, based on hands-on activities, are organized into five areas: "see", "do", "explore", "holo kids" and "to know more". The holography lab is based on a portable Denisyuk system and it allows the public to notice the typical darkroom environment needed to work on holography and also it allows visitors to make holograms as a souvenir of the exhibition. There are two types of visits: "Exploring the world of holograms" focus on visiting all contents and "Let's make an hologram" that, besides visiting, allows also to make holograms. Light Windows is an exhibition dedicated to the general public that during the last year has been traveling around six Portuguese cities. This paper will present and analyze all results obtained and it will discuss exhibitions impact on visitors.
