Even though MIUI has been around for years on Android, it's regularly being updated with new icons. MIUI v5 has been around for a few months now but we think it's something worth covering because we like to only recommend the highest quality Android icon themes.
If you've never used MIUI before but love colourful icons, MIUI 5 is one of the best. The icons are absolutely gorgeous, using some very nice colours that are pure eye candy. The icons are also very detailed when they need to be but flat at the same time. You can see from the screenshot below, how much detail has gone into the maps icon - it's that sort of attention to detail that we care about when it comes to icons.
MIUI 5 is free on the Android market and will work with most custom launchers.
