DTS "Waterdrop" Logo (1995, Kinemaster Recreation) 

Waterdrop is the second promotional/introductory trailer for DTS. It was made as an alternative to Stand Alone (also known as "The Digital Experience"), intended to be shown before quieter films in which the loud nature of the aforementioned trailer was not well-suited for, however, since similarities to the Imagine Entertainment production logo lead to said company threatening to take legal action, it was recalled almost immediately, and only seen in three theaters in both St. Louis and Albuquerque. The audio for the trailer had managed to slip past the trailer's recall, as DTS audio discs for May 1996 film releases such as Twister, Mission: Impossible, and Dragonheart.
This is my recreation on how I think the actual logo looked like. It may not be entirely accurate to the real trailer.
