The Ancient Filipino Writing System: Baybayin

I was first briefly introduced to the ancient Filipino writing system known as Alibata in one of our Kasaysayan classes in UP. Never had the chance to explore it at all... but recently, I stumbled upon a site that teaches how to write Baybayin. I am curious to know whether Alibata and Baybayin are one and the same....the sites I checked say they are the same. But, I remember seeing Arabic-looking symbols for Alibata.  I hope to find the time to look into this deeper....

In the meantime, here are some sites I found on Baybayin.
