What are the bell shaped structures in the floor of the PAC?

The look like old school flat pancake bells you'd see @ elementary school.  I'm assuming they are AC vents?

Oh and bright idea letting D-fest FACE the PAC during Wicked.  The bass was a bit annoying at times Oh well, it wasn't THAT distracting, but I'd have been pissed if I was one of the performers.

I wondered about that.  Who scheduled these two on top of each other?

You do know DFEST was IN the PAC too, right?

Went to 2 of the D-Fest concerts in the PAC.  As for the "bell shaped structures in the floor" would have to see a pic. I dont think I have noticed anything like that before.

One of my friends posted on Facebook Saturday night: "we got to see Wicked and listen to DFest all for one ticket price."
