For a couple of months now, I worked with the Unreal Development Kit (UDK). It is a game simulation engine and a really nice piece of software.  The UDK has grown over the last several years continuously in functionality but it  never was redesigned.

I sat down and created an interface framework and environment that is visually consistent just for fun. I got my Inspirations from the spirit of modern software like Photoshop CS6, After Effects and zBrush. Influenced by those programs that spend huge resources on good interfaces I decided that the UDK needs also a color change and so I used a color scheme similar to the upcoming Adobe CS6 programs.

I created most of the icons but I also used several icon resources for inspiration:

Crystal Clear, Farm-fresh,  Gnome icons,  Fugue Icons, Project icons
