And the reason you can't see them is they are the same tannish-brown color as the background. I can see them because I'm colorblind.

You can easily figure this out: all rotation matrices have determinant of 1 (so they are what's called orthogonal matrices). In fact, you can see that this matrix has determinant of -1, so technically it's not a rotation but some combination of reflection and rotation.
