One benefit of running a custom launcher like Nova or Apex aside from cleaning up your device and performing the overall speed of your home screen is the ability to add custom icon themes. While they won't change up the system ui or framework of your phone's rom icon packs do give your phone a whole new look and feel which can really freshen things up. The Lyra Icon pack by theme dev "artvandelay440" has just been updated. It includes a handful of new themed app icons, and lots of bug fixes!
The Lyra icon pack brings to your home screen a subtle gradient, tasteful glyphs, and minor shadowing. There are 760 hand themed icons, 37 cloud based wallpapers which won't take up space on your phones internal memory, an exclusive dashboard app, an integrated request tool just in case your favorite app is not themed, muzei support, and behang b-link support. This icon pack should be compatible with most custom launchers. Grab the icon pack from the link below.
