The best example of non-euclidean geometry is the globe. Lines of longitude are parallel at the equator, but converge at the poles, in defiance of Euclid's geometry. This derives, essentially, from the curvature of the space on which the lines meet, the interaction of two-dimensional and three-dimensional spaces. It's relatively easy to understand in the abstract, but becomes more difficult to grasp in the concrete.
