Gengi.is (Minimalist Currency Converter)

We at Form5 (http://www.form5.is/) recently launched this minimalist currency converter for the Icelandic Krona. It's designed using colors and typography from our own branding, but somewhat inverted.

The focus was to make a mobile friendly converter with a seamless user experience and we used various methods to achieve it, such as animation and quick page transitions, pre-selected input boxes with the default state at 1 krona, as well as building it using AngularJS; Google's framework for building single-page web applications
