And yet the main image on the article illustrates a 45 degree rotation along an axis. From what I understand, you are saying this rotation is non-intuitive. Co

  I would say that one can still interpret it geometrically, but the difficulty is that it's not in 2D or 3D, but in a higher dimensional space. Imagine you have a population of 100 neurons. To each one you associate a real number representing its activity. So a particular snapshot of firing would have 100 real values. It's a vector in a 100 dimensional space. Each individual neuron is one dimension. The high dimensionality of the space is what makes it unintuitive. But, after some familiarization you learn heuristics for reasoning about high-dimensional spaces and combine that with your 3D spatial intuition. The 45 degree rotation is just some nice art, but you could think of it as representing a projection down to 2D.
