You can probably mask out and break apart individual letters, and then write an expression for orientation and position over time to move along Z space, and "wiggle" a little.
Then you can add some motion blur, and some dynamic shadows.. also, give it a radial ramp on the text and some curves adjustment to make the lighting look the same as the scene with the window.
Not sure if that's the "easy" solution you're looking for, but it would give the effect you are wanting.
:S all i wanted was to try and get a text animation file
Create a text layer, apply shatter, set the shatter render to full....
Do you need a project file?
