You can attend a play (fingers crossed) or watch a movie to learn about Shakespeare. On the other hand, if you want to learn about the second law, Peter Atkins's book on the subject is a good place to start.
The key point about the second law is that although energy is conserved, the distribution of that energy changes in an irreversible manner through time. This leads to certain asymmetries in nature such as the spontaneous cooling of a hot object (but not the spontaneous heating of a cold object). By extension, the construction of new buildings and growth of plants comes at the cost of destruction elsewhere.
In some sense, then, entropy is the subject of the photograph above. With the leaves gone for the season, we can study the manner in which the vine tries to cover the surface of the wall. The greater the coverage of leaves, the more energy available to the plant through photosynthesis. Humans apparently prefer to build using Cartesian geometry as a guide whereas plants are more free form or 'organic'.
What is also interesting is that apparently different species tackle the problem of surface coverage using different approaches. The plant in the image below has taken a more 'vertical' approach.
One last thing to consider: Why would you let vines add entropy to your house like that! :-)
