Want to add some holiday magic to your festive snapshots? Glitterboo is a new online service that allows you to paint animated effects onto your personal photos. From glitter to stars, there's a range of tools and effects you can add simply by painting them on and clicking "apply". When you're done click on the "Select Size" icon to move to the page where you can download or embed your finished photos. You can use a selection of effects and sizes for free, but will have to pay a $10 membership fee to access the entire catalog.
