That would be the Masonic square, compass, and letter G.
As for Lane Stadium it's a pretty well put together place. Been there a few times to watch games really wish I could get out there to see the VT vs. Miami game as Miami is probably just as big a rivelry as UVA. It's so bad if you listen to the Miami broadcasters on the radio they don't go to Blacksburg they go to Blanksburg to play. They are also the ones that tried to block VT's way into the ACC a few years back saying if VT went they weren't gonna go.
But when the place gets cranked up you don't even hear yourself think.
