Apple's new Upper East Side store on Madison Avenue in New York City has been many things since it was a bank.<br />Today its second floor, which is below ground and still houses the bank's vault, is a makeshift school and temporary way station for Apple CEO Tim Cook.<br />Cook's arrival on Wednesday is perfectly timed to coincide with an Hour of Code session with 18 students from the city's PS 57 James Weldon Johnson Leadership Academy, a Charter School in East Harlem.<br />For many of the children, this was their first experience with programming.<br />“I was limited in my knowledge of what we’d be doing,” PS 57 third-grade teacher Joann Kahn said.<br />“I’m excited for my students.<br />It opens their eyes to other possibilities and shows them that there’s more to do with iPads than just watch YouTube videos.”
