Hmm... By Holly

A giant pyramid, just the side/corner of one, so they could go inside and read by flashlight-lantern.

Or white "marble" columns, draped fabrics, grapes, urns, leaf-crowns (word escapes me!)...

Whichever you choose, find some period-type music to play in the background, that would be cool for Parent Night, or whatever, lol, with special lighting.

Fun!
