What's a dorna?

Sorry for what to the rest of you is probably an obvious question, but I'm a newbie here. Will somebody please educate me on this?

it's the signs/ads that scroll near the floor of the stadium

Thanks. Never knew those things had names. I used to do stats with the Magic and all I knew was not to stand to close to them.

well, for sure, I dont know if they are actually called dornas or not. The texture name in Live is dorna, so that is why we call it dorna

anyone else? am i wrong?

I assumed that was their proper name. They adorn the sidelines, perhaps it's derived from that?
