Rotating objects controlled by scrolling

Question

I would like to see scroll motion to control the rotation on an object. Scrolling would make an object rotate while staying in the same center point location. If this is already possible, please let me know!
Cheers,
Ingrid

Answer 1

here you go, 5 copies
50 copies
#target Illustrator
//  arranges duplicates of selected object into a spiral
// step is 1.1 cm - 17 degrees hardcoded
// select object before running
// CarlosCanto 3/1/11
var idoc = app.activeDocument;
var isymbol = idoc.selection[0];
var teta = 0; // initial angle
var r = 1*28.346; // first dup, // 1 cm = 28.346 pts
var deltaTeta = 17; // angle increment
var deltar = 1.1*28.346; // distance increment
var a = prompt ("how many copies", 5, "Spiral Symbol Duplicates")
for (i=1 ; i<=a ; i++)
          var dupSymbol = isymbol.duplicate();
          var deltaX = r*Math.cos(teta*Math.PI/180);
          var deltaY = r*Math.sin(teta*Math.PI/180);
          dupSymbol.translate (deltaX, deltaY);
          r = r+deltar;
          teta = teta+deltaTeta;
