The revamped MoMA invited people to visit for free on Sunday, before the official opening. Nearly 10,000 people took the museum up on its offer, and they needed to create new mental maps. “As they entered the new expanded lobby, many gravitated toward the electronic information sign — with columns labeled ‘West,’ ‘North’ and ‘South’ — to decide which way to go. Staff members wearing neck lanyards and carrying maps approached visitors with friendly ‘Welcome to MoMA’ greetings and offered to help direct them. But even employees seemed a little unsure of themselves. ‘Is there an elevator that way?’ one visitor asked. ‘I think so,’ answered a staff member, opening one of her maps, ‘Let me check.'” – The New York Times
