Make a cylinder that looks like a record or a CD.

Place this script inside...

<lsl> integer spinning;// = FALSE;

default {

   touch_start(integer num_detected)
   {
   //  toggle between TRUE (1) and FALSE (0)
       spinning = !spinning;

       if (spinning)// is on turn it off
           llTargetOmega(ZERO_VECTOR, (float)FALSE, (float)FALSE);

       else// turn it back on
           llTargetOmega(<0.0, 0.0, 1.0>, -PI_BY_TWO, -0.01);
   }

} </lsl>

How llTargetOmega works...

for the function that reads: llTargetOmega(<0.0, 1.0, 0.0>, TWO_PI, 1);
The first parameter is axis of rotation expressed as a vector (<0,1,0>) which will rotate the prim on the Y axis
To change the axis to x <1,0,0>... to change it to z <0,0,1> and to reverse direction <-1,0,0>, <0,-1,0>, <0,0,-1>

The second parameter is the rate of rotation in radians per second.

The third parameter is the gain. (should not equal zero - subtle effect)
