This is a very nice hand specimen showing a gneiss that has been folded (at least) twice. Obvious is the very prominent oblique fold in the center of the specimen. However, if you rotate the model around somewhat, you can see that the foliation planes are warped in more than one directions. There is another, more subtle set of folds at almost 90 degrees to the first one. Combined, they give rise to a dome-and-basin structure.
