kovdev: Nox and Lumos
kovdev's mission statement is “to provide users with an assortment of design options to personalise their Android devices,” and it delivers on this. The Dave Kover and Ben Lee combo has created a series of icon packs which complement Action Launcher Pro.
The only problem is selecting which one to download as they cost $US2.23 each.
The first and second screenshots in this slide are of the Nox and Lumos apps, respectively. Nox contains very simply square icons with a hint of a shadow from each. Lumos is reminiscent of Apple's round-edged icons.
All of kovdev's designs are very similar to the originals, but offer a unique twist. Not all icons are supported, though; those which have not yet been addressed utilise the app's default look with a border. Credit must be given to kovdev for very frequent updates which are rolled out at virtually the same time to the team's full portfolio.
The best part is that there is not only one messaging icon or one phone icon -- a full arsenal is at hand, allowing you to further customise your experience.
