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.
