Luxury brand Swarovski has launched a synthesizer app that lets you create compositions in light and sound by playing around with the touch screen.

Swarovski Refract is a visually stimulating digital application that's available on the iPhone and iPad. It's been developed by digital and human interaction specialist Marek Bereza and musician BobbyKrlic. The app lets people use the touch screen to create a triangle with three shining points. These can then be moved around, resized and multiplied in order to change sounds and colours.

Luxury brands continue to engage with consumers through the use of digital technology. The Swarovksi app is an example of how this can be achieved, and how apps can let people explore and play around with the form of luxury products.
