The New York Times provides a photo gallery of the new Administration's senior appointees.  (HT: Chris Cillizza.)

Run through it to get a sense of how great the ambitions must be on this the first full day of the Obama era.  I wish we had a link to a similar photo shoot from the first day of the Bush Administration, when 9/11 was only months away, and the realities of the world not yet fully appreciated.  If this team can continue the departed team's record of keeping the country safe from a second catastrophic attack, they will have accomplished a great great deal.  If they don't, nothing else will matter.
