This script will create text with each letter having a different font. Options include user configurable font size, choice of text output options, choice of filter for random font selection, background pattern, random rotation of each letter, bumpmap, letter outline, curl, locked text color and font, bumpmap, chisel and inner shadow effects and text layer merging.
The download includes some nice paper patterns. If you place them in your patterns folder, paper_4 will become your default pattern.
With the Menu length you may need to install the script-fu scrolling interface
