Hi all,
I'm looking for a way to do this: Show text where the letters are positioned randomly across the screen. Then gradually move the letters towards their correct position, to show the original, readable text... any suggestions? Thanks!

IIR: next position := current position * 0.95 + 0.05 * target position (will never reach target exactly)
FIR: current position := start position * (1-t) + t * target position (with t in 0 .. 1)
You need one of the above for each coordinate of each letter, so I suggest storing the information in arrays (or data structures) and looping through them.
