well i used the search for this topic and nothin so forgive me if i'm wrong ......but the title pretty much narrows it down.. animated interfaces....for Example say your life is very low and it'll show your health bar drippin blood or smoething like that......basically it would be like using .gifs....and truthfully i don't think it would be that hard to put on... if you can program it on a website then it should be able to work in the game
