Galaxy Nexus users will be happy to hear that a new theme is available for the ICSourcery Rom! If you have ever flashed ICSourcery then you know that not only is it one of the fastest and stablest Roms around, but it is also one of the most customizable Roms around! One of the coolest features is the Theme chooser. The theme manager in this Rom is not the same as the T-mobile theme engine, although it includes that too, the theme manager in ICSourcery includes all kinds of themes that have been developed specifically for this Rom! The latest theme from ICSourcery Themer "Alastrionia" is looking pretty SICK indeed! The Mystify theme is compatible with all 3.4 variants of the rom, but is not compatible with the 3.5 linaro build.
This theme is incredibly thorough. It seems like every aspect of the UI has been totally redesigned for this theme! There is pretty much no part of this Rom that hasn't been modified in some way. The attention to detail here is just astounding. Who knows how long it took to replace every single image that has been replaced. Some elements that have been themed include System UI, Framework, dialer, nav buttons, drop down menu, notifications, notification bar, gmail, settings, sms, calendar, calculator, app icons, and so much more!
Installation is simple just Install ICSourcery 3.4.x, then go to ICSourcery Tools, then Theme Manager, and select Mystify.
