You wanted to know about a good way to animate.

I wrote a package, which lets you fade in and out templates, by simply adding {{AnimateTemplate "templatePlaceHolderName"}} and set Session.set('templatePlaceHolderName', 'templateName') to render and fade in a template.

CSS3 transitions have to be added manually. This way you can animate your templates however you want.
