That's a standard tetradic (four-part) diagram.The circles with faces show some similarities with this, especially the ones on the T-O diagram and the ones that form a cross. I think there are some arguments against the interpretation as tetradic diagrams though.
* Variation in number and arrangement: triangle (3), U-shape (4), L-shape (4), cross-shape (4).
* Labels: the whole is labelled, not the individual circles. In a tetradic diagram, the focus of the labels is on the individual parts, i.e. "this is water, it is wet and cold".
* In the same vein, the cross looks most like a tetradic diagram but its faces are pretty similar. This suggests again that the focus is on the shape of the arrangement rather than the individual parts.
This is not entirely conclusive since some of the faces (like the one with the pointy hat) are unique. However, their overall similarity and especially the fact that only the group is labelled seems to suggest that especially the arrangement of the cluster is important.
