Desire dictates form. Form is not directly chosen yet is persuaded towards functional intent. Rules are not broken, instead they are taken advantage of to express the new.
I absolutely love growing plants in my courtyard. It's to the extent that I can barely walk around the area. There are vines sprawling all over the yard right now. One of my favorite plants from this growing season was my mammoth sunflowers. Some of these things grew up to 14 feet tall or so, well above the eaves of my roof! The best part, of course, were the flower heads that were more than a foot across.
