The holiday season is all about giving and caring and all those warm and fuzzy feelings, but for the Humbugs, it’s a time to be grumpy, greedy and downright rude!

Zehnder Communications, an American design firm, is using Layar to bring their latest creation, the Humbugs, to life. These fun-hating killjoys are featured on a set of free printable paper Christmas tree ornaments that spring to life in all their nastiness when scanned with the Layar App.

“These crude-rude, seedy-greedy creatures slink about in mockery of this most joyous season. And now it’s time to take a stand,” Zehnder’s website declares. “This year, Zehnder has devised a new way of exposing the Humbugs by adding a little cheer to the holiday at their expense.”

You can even battle against the Humbugs in a side-scrolling adventure game! But the real fun comes from seeing the paper ornaments come to life when you scan them with the Layar App. Enjoy!

About Zhender: Zehnder Communications, a full-service advertising agency, was one of the first agencies in the U.S. to venture into Augmented Reality in 2009 with its Voodoo Music Experience app. The app, featured in Fast Company, was one of the first of its kind — innovative apps for brands like Sony and Disney parks soon followed. Zehnder serves clients across the country from its offices in Baton Rouge, Nashville, and New Orleans. The agency was founded in 1996.

It’s that time of year again. The most wonderful time of the year, as the song goes. A time to reconnect with friends and family and reflect on the past year over delicious food, thoughtful gifts and fun in the snow.

For Layar, this has been an amazing year of growth in which we have grown out of our infancy, but that doesn’t mean we still can’t have a little fun once in a while! That’s why we’ve created a special interactive layer for the Christmas holiday.

Fire up Layar on your iPhone or Android device and search the catalog for “Xmas Layar” and you’ll find a layer made for us by our friends over at C2K. No matter where you are, you are immediately encircled by photos of the entire Layar team. Clicking on one our photos will let you see Christmas wishes from each of us. If you’re feeling mischievous, feel free to toss a snowball at us. It’s okay, we won’t be mad, it’s all part of the holiday fun!

If you like you can send us your own wishes or responses via email from the layer, and keeping with the spirit of the holidays, you could win a gift from Layar. The three most original Christmas wishes we receive will be awarded with a Layar hoodie sweatshirt, so go ahead and share your wishes with us!

As for us here at Layar, we are very excited for what 2011 will bring for the community, and we can’t wait to help usher in the next wave impactful Augmented Reality experiences. Happy holidays and happy new year to all!
