I was going to recap everything APhiA did for our centennial, but it's already on Wikipedia for anyone who wants to see.

I will add that in addition to the things mentioned, we published a massive 700-page book called the Centennial Book of Essays and Letters (a must-have) and had a lot of neat convention gifts like a leather (?) bag, medallion, pin, etc.
