History of the Letter A

The letter A is the first character of the alphabet and has been since our alphabet was adapted from the Egyptian language and then from the Phoenicians. The entire alphabet has progressed a long way since the beginning thoughts of writing and letters. A few web pages that I found demonstrated how the capital letter A, was pretty much always formed with three lines, but the look of this formation has changed a good deal. At the same time, many ancient forms of the letter A were formed like an open triangle, and several lowercase formats look like today's English u. It seems also that most formats were designed from the modifying formats that came before them, such as the rustic capital of which the capital A gains feet on the bottom of the two large meeting lines but there is no middle dash to complete the A we are now familiar with. I learned from another article a theory on the possible origin of the letter A from the Phoenicians, which is that they used the ox head to start their alphabet thus the letter A represents this picture and starts out their alphabet in a very strong manner.
I am interested in the letter A mostly because it can be written in so many ways to still be interpreted as the same letter; I also find it interesting that this letter or any variation of it always starts off the alphabet and seems to be used in abundance when reading through any article, book, paper, ad, etc. I think that an animation using the letter A can show people the variations of the letter, and the many looks, whether in size, format, color, shape, or angle, that it can hold on a page. I hope to use animation to make the letter A appear as a flowing format of my own, that can dance around a page and put its feet to good use.
