I have a special affection for store front windows that are completely filled with a monster plant. Perhaps there is a lot of nitrogen or some kind of growth hormone in the chemicals used in dry cleaning because they tend to be the most popular businesses supporting gigantic plants. There is one nearby to where I live with a rubber tree (Ficus elastica) that is literally crawling along the ceiling in a million tangled appendages.
In Santiago de Cuba we found this bookstore window completely overrun by a pothos. Bonus points because the name on the window is also botanical.
