4x4 Quad Color Boxes
At first this looks like a rotation around a single corner, but the cubie placement is a little more complex to allow four colors per side. An ordinary rotation pattern has no more than three colors per side.
Another distinguishing characteristic is that all six face colors are visible from each of the two views.
This is a Meffert's Master Cube from the mid-1990's when they were using tiles in a color scheme with red opposite white.
