Christmas is going digital at the White House this year.
The holiday decorations unveiled Wednesday include 3-D printed ornaments that were designed by students, tinkerers, engineers and artists from around the country.
There's also an interactive installation in the East Garden Room that allows people to visualize themselves in a snowscape projected on the wall.
This year's theme for the White House decorations is "a children's winter wonderland.''
Another new feature this year is in the Vermeil Room, where two Christmas trees were created from dress-form mannequins.
Overall, 26 Christmas trees are on display, and there's more than a mile of knotted ribbon in the animated replicas of first dogs Bo and Sunny.
