I'm looking for a technique to create a window with letters that drop from top to bottom, forming words as they go.
This is similar to the scroll screens used in the Apple Retail Stores.
What language(s) should I use? Are their techniques I can pluck?
Many thanks.
There is a wonderful resource that has been developed over the past ten years by a french programmer: Gerard Ferrandez. The site is http://www.dhteumeuleu.com/.
Specifically, Gerard's javascript technique to show falling letters is here:

All of Gerard's work is open, and I urge anyone who uses this material, to contribute something.
