Are you away from home or just aren't able to decorate your Christmas tree? Have you never decorated your very own tree, or just can't stand the idea of all that messy work? Well, this application let's you enjoy this holiday tradition over and over again as you decorate very own Christmas tree anywhere and anytime you want.
Choose from several different Christmas trees and backgrounds. Next begin decorating your tree by adding different types of bulbs and hanging them on the tree. Then add your light streamers and choose from various tree toppers and you're done. You can even spin the tree to decorated from all sides. To start over again just shake back and forth and your decorations will fall away.
