Sensory Abstract#2 app is the second abstract app in what has become a series of visual digital art and sensory effects. The app is a combination of the use of digital art and effects techniques created by Sensory over the years, alongside the influence of abstract expressionist artists. The concept for this app is to create a calm, visual experience, with slow emerging shapes. There is a vast combination of layouts and colours to enjoy, and a range of styles pressing the left/right arrows. Sensory Abstract #2 is a moving display of unique digital effects combinations. The projection capabilities of the phone or tablet gives the option for galleries, sensory rooms, theatres and relaxing environments to run the app on large screens. Just choose the effect you prefer, using the on screen buttons and let it flow. Tap the screen (or press 5) and the on screen buttons will disappear. You can control the app with the bluetooth keyboard characters 1,2,3,4,5, +, - , space bar and enter key. This also allows any bluetooth access switch systems that can deliver the above characters to the computer. Keyboard 1 (button 1) or Space Bar changes the background effect Keyboard 2 (button 2) changes color of the main effect Keyboard 3 (button 3) or Return/Enter key changes style of the main effect Keyboard 4 (button 4) changes symmetry of the main effect Keyboard 5 (screen tap)) hides and shows control buttons + & - change to the next or last abstract visual if available Sensory Abstract#3 contains no adverts and does not require a login.
