I've recently finished designing a collection of 50 wallpapers made for iPhone home screens. Without app icon shadows, iOS 7 can make the home screen look quite cluttered. I started with very simple ambient colour spectrums and decided to make a few more.
Beautiful wallpapers by Thomas Ricciardiello (via Mike Rundle). I'm trying one of the Light Spectrum ones on my iPhone now (I've been using an Apple default one since September). It'd be great to have iPad versions.
