David Rowe has been building a version of the SL Viewer, well, the Firestorm version of the SL Viewer, that supports Shutter glasses and the Oculus Rift. These versions are labeled experimental., probably for multiple reasons. There is no doubt the viewer is experimental for the very obvious reasons the Rift has yet to be officially released and the Lab has yet to release a viewer with Rift support.
David has deliberately avoided doing much with the user interface for his Rift supporting viewer. His intention was to wait until the Lab released their viewer. I suppose with a base UI established a decision could be made whether that wheel was round enough or needed improvement.
