The display library that MageGuild (and possible upcoming projects) is based on has been renamed Phasma, and is now available for download. This includes full source code and a demo app, to show off what it can do and how to make it happen.
Phasma is available on its project page.

Is this a bug, or is it just how the demo was coded?
