(California)〔Light Shows. http://www.hirshhorn.si.edu/visualmusic/lightshows.html〕〔(The Single Wing Turquoise Bird )〕〔(pOoTer's pSycheDelic shAcK - Lightshows (Single Wing Turquoise Bird) )〕 ==Brief history== Liquid light shows surfaced on both sides of the Atlantic around 1966 and were an integral part of the Progressive music scene well into the seventies. Shows could be as simple as a single operator and two or three modified slide or overhead projectors and a couple of color wheels or as complex as shows with ten or more operators, 70 plus projectors (''including liquid slide, liquid overhead, movie and still image models plus a vast array of highly advanced (for the time) special effects equipment''). The style and content of each show was unique but the object of most was to create a tapestry of multimedia live event visual amplification elements that were seamlessly interwoven, in a constant state of flux and above all, reflected the music the show was attempting to depict in emotional visual terms. While the shows on both side of the Atlantic had much in common they differed in two important ways. First, the American shows tended to be larger, with seven operators and over thirty projectors not being exceptional. In contrast, the shows in England seldom had more than three operators and ten or so projectors. Second, American shows were generally built around the overhead projector with the liquids in large clock cover glasses. Shows in England and Europe, in contrast, used modified 2" sq. slide projectors which had their Dichroic heat filters (one or both) removed and employed two layers of slide cover glasses with two liquids (oil and water based, in the early days) between each layer. The surface tension of the liquids largely retained the mixtures, but the process was nevertheless very messy indeed and operators had their hands almost permanently stained by the dyes. A popular choice of coloured liquids for lightshows was Flo-Master ink, a product developed for use in permanent marker pens. While this ink was very vivid it also had the problem of staining the operators hands very deeply. Two groups that are associated with the light shows they worked with above all others are Jefferson Airplane and the Headlights light show in America and Pink Floyd with light artist Mike Leonard in England.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Liquid light show」の詳細全文を読む スポンサード リンク
