I just created a project for a Raspberry Pi based MFD as part of a set of KSP controllers. In a way, the more interesting part of that project is the software running on that MFD. Specifically screens showing the 8-ball/FDAI, orbital parameters, resources, etc.
The goal of this project is to have a live interface that takes data directly from KRPC, and so can be used for navigation. So far, the project includes a static HTML and SVG interface visually similar to the MFDs in KSP (credit to RPC and ASET for these). The interface also uses ThreeJS for the 3D 8-ball element. This 3d element allows the element to be rotated so that attitude angles can be fed to the interface with a minimum of maths. Here's a clip of it in action (although this just rotating at a fixed speed - not connected to KRPC):
