a small treasure hunt to lay the foundations of the first domus of Rome by Romulus? Or maybe to trace the Pomerium meter after meter?
I have been around AW only for some months and maybe it has already been done, but I was thinking of something on the kind of what our friends in the Americas did with the "The Great American Igloo Building Eventduring Goldfest '06. I haven't got very deep knowledge on Rome's foundation, but maybe someone from the Fundamina Romae group could come up with something accessible and humorous?
