Just in case you aren’t familiar with the term, bokeh basically refers to the out of focus bits when you take photos with a camera. Usually bokeh tends to be more pronounced when using cameras with a larger sensor, like a DSLR for example. In this case the theme appears to be focused on lights that are out of focus which is admittedly rather classy.
Given that this is a Premium theme, it also means that it isn’t free. It is currently available for download for Xperia devices via the Google Play Store where it is priced at $1. Granted it is a small price to pay but if you’re too lazy to theme your phone yourself, we guess that’s the price you’ll have to pay to get a more personalized look for your phone. Alternatively there are apps out there that provide free themes, or like we said with the right tools and launchers, you could make a theme for yourself for free.
