this is a cool effect
you could improve the preview thought 
This is a cool mouse effect, that is easy customizable with documentation on how to use inside the action script along with a help file.
To use:
1)Go to the help file and follow instructions
2)Once in the flash-> Press ctrl+f hit the checkbox that says match case then type in eFg234
3)Copy and paste the code
4)For the code to work go back into the original flash called trigMx then copy and paste into your own project the movieClip in the libary (copyMe)
5)Go to the libary right click copyMe and press linkage
6)Once done with that hit the checkbox that says export for action script
7)Type in the identifier box “ball” all lower case
The code should work perfectly.
Variables to edit: var frameMax:Number = 10; Amount of frames in your movieClip
var num:Number = 5; How many copies of the MovieClip you want
this.dist = 200/num2 The length of the string (200)
one Varriable [ this._xscale = this._yscale=Math.atan2(this._x-_root[“b”+this.parent]._x, this._y-_root[“b”+this.parent]._y)4; ] The only thin you need to worry about is (*4) It determines the size of the images To increase simply make 4 a bigger number.

Nice file! I agree about fixing up the preview a bit, it doesnt do the file justice. I would say get rid of the text that you need to backspace out to type in the numbers, and just make it look like a well defined text area…and then say “type in a number 1-199” rather than type “higher than 0 and less than 200” makes it a little easier to get to the meat and potatoes of the file. Also maybe have it default as the preview and then allow a button to be clicked to customize the line.

Oh, I was gonna do 1,000,000,000 but then I remembered it only goes up to 200.
