variant:cascade is an audiovisual artwork that creates beautiful, ever-changing music and imagery. The app combines user input and built-in randomness to create images and music that will continually change, grow and evolve, offering a new and different experience every time. For users of all ages, variant:cascade is a chance to explore and experience a unique work of generative art. variant:cascade was specifically designed to take advantage of the 3D Touch sensor on the iPhone 6s and 6s Plus: increased pressure on the phone’s screen will intensify and transform the visual and musical experience. To interact with variant:cascade, draw a line with your finger on the screen and the visuals will respond to your drawing. Pressing more deeply on the 3D Touch screen will change the width and speed of the visuals as well as transform the music. (Users on devices without 3D Touch can vary how much of their finger touches the screen to trigger this effect.) You can use multiple fingers to interact with variant:cascade, and each will independently influence the visuals and music. You can view the indeterminate audio engine by tapping the dot in the lower right. The display shows the different elements of the musical composition as they are loaded by the engine through a combination of chance and user input. The center button opens a menu of settings for the app, and the button to the right allows you to take screenshots of the visuals, automatically saving them to your photo library. The Variant apps are a new series of generative audiovisual artworks from Interval Studios featuring visuals by Joshue Ott and music by Kenneth Kirschner. Each Variant features a unique visual composition by Ott based on his superDraw visual performance software, as well as a new indeterminate musical composition by Kirschner. Each Variant app also offers a different set of interactive controls for the user, ranging from the ability to subtly influence the development of the piece to total interactive control over both visuals and sound. All of the Variants are generative artworks: through a varying combination of built-in randomness and user input, each Variant will continually grow and evolve over time without ever directly repeating itself either visually or musically, offering the user an ever-changing, ever-evolving audiovisual experience.
