Grid

This isn’t the exact wallpaper shown on Lukas Mathis’s iPhone, but it’s “loosely based on an idea by the Effektive Design guys”.

Effektive Studio:

These grid inspired layouts act as an organised wireframe structure to keep your applications in neat and tidy order on your iPhone. With numbered grid rows and a ‘D’ for Dock you simply press hold and drag and drop your icons into the specific grid spots.
