Horizons [iPhone, iPad, oF]


Horizons is a interactive sound toy which brings together the atmospheric sounds of Eli Murray (Gentleforce) and generative visuals of Lukasz Karluk. The app is an exploration of colour, sound and form.

The design of the piece focuses on creating subtle colour refractions in a rich colour scape using an algorithmic process known as triangulation. Fluidity of interaction is achieved using real-time physics made using the Box2d library and openFrameworks.

Using the UIKit (Apple GUI standard) in combination with oF, you are able to modify a number of parameters in the app. These include the amount of points triangulations use, the colour of gradients as well as randomise the colour and save screens to the library. The triangles themselves react to accelerometer and are multitouch allowing you to move multiple points at the same time across the screen.

In the process, Lukasz has also made some of the work available open source, including the colour picker code which you can download here. Mac version of the app + source coming soon..

The app was finally released today. We have had it for few days now and not only thats it’s a joy by itself it also works great in combination with other apps if you are looking for some awesome looking gradients. A must for your app collection..

Gentleforce has also recently released his debut album “Sacred Spaces” on Feral Media which can be downloaded from iTunes.
