letters come in from the edges of the screen

Is there an effect that would do this:

Some letter come in from the lower left, some from the
upper right, top, bottom, etc. and then they would all float towards the
center of the screen where they would meet up and form the words.

I think that the "FETMagneticWind " or "FETIndustrial" patterns are very near of your description.
Here is a link with all flasheff patterns which are available for the moment:
