**Caption:** This is a picture of curvature, that is, after one loop of parallel transportation of a vector (the arrow), there is a finite deviation. You may feel puzzled and then realized that the world is curved. Interpreted in terms of gravity, the curvature is due to the mass, namely, the person wearing the T-shirt. Since curvature is a signature of non-trivial topology, and 'topology' is currently hot among the physics community, then it can also be interpreted as 'the world is crazy about curvature.'
