The best way to describe Aurebesh is that it is the alphabet in the Star Wars world. Follow the related link if you want to learn how to read Aurebesh.
The alphabet in Star Wars is called "Aurebesh"
There are 34 letters and 15 different punctuation marks.
Aurebesh. This derives from the 2 first letters (Aurek=a, Besh=b), as "alphabet" comes from aleph/alpha and beth/beta.
If you mean the font that we constantly see in the show such as on the screens and such, that is Aurebesh and it is the basic alphabet for English (which is called "Basic" in the Star Wars universe)
It does not appear that LucasArts has asserted copyright over the characters themselves, but designers of available fonts do assert copyright over their work (e.g., David Occhino's 1997 version carries a "single-user, non-commercial license for personal use").
The flying effect actually doesn't have anything to do with the font. That's a movie effect, like how there's animation options in Microsoft PowerPoint. The font, though, has no real name because it has never really been released to the public by LucasArts. However, search "starjedi+font" on Google and you can download the font; somebody else managed to create the font.
