Feliz Navidad from the Forsyths!
This was a project for Christmas 2013, in honor of our upcoming move to Spain. After cutting out letters from cardstock, I took a series of photos of various family members, aligned and modified them in Photoshop (if you look closely, you'll see that the youngest is levitating), and saved it as an animated gif.
I just set it to animate twice, to decrease the chance of it driving you bonkers. If you'd like to see it do its thing again, reload the page while holding the shift key.
