While many see only an open book, the true depth of this mark lies in its hidden symbolism.
The "pages" were designed as palm fronds, reflecting the Miami environment. Notice the middle page: it's turning in motion, symbolic of education progressing one page at a time.
Simultaneously, that middle page forms the "world" surrounded by an orbital path that represents space exploration and high tech advancement. This combines a futuristic, high tech curriculum with traditional "book" learning.
