Here is a Speedometer I made this morning, because I got bored. It will Give your speed in KPH, rounded to the nearest KPH. It works by subtracting the x, y, z values of the current pos, and the pos from 0.5 seconds ago. it then works out the horizontal distance traveled,

square root of (square root of( (x1*x2) + (y1*y2) ) * square root of ( z1 * z2 )))

And here is the code:
CODE
`vector current;vector new;float xvalue;float yvalue;float zvalue;default{    state_entry()    {        vector current = llGetPos();        llSetTimerEvent(0.5);    }        timer()    {        new = llGetPos();        if ( new. x < current .x)        { xvalue = current .x - new .x;        }        if ( new .x > current .x)        {         xvalue =  new .x - current .x ;        }          if ( new .x == current .x)        {         xvalue =  new .x - current .x ;        }                                if ( new.y < current .y)        { yvalue = current .y  - new .y  ;        }        if ( new .y > current .y)        {         yvalue =  new .y - current .y ;        }         if ( new .y == current .y)        {         yvalue =  new .y - current .y ;        }                                        if ( new.z < current .z)        { zvalue = current .z  - new .z  ;        }        if ( new .z > current .z)        {         zvalue =  new .z - current .z ;        }         if ( new .z == current .z)        {         zvalue =  new .z - current .z ;        }                float beforevalue = llSqrt((yvalue * yvalue) + (xvalue * xvalue));        float aftervalue =  llSqrt((beforevalue * beforevalue) + (zvalue * zvalue));                llSetText((string)llRound((7.2 * aftervalue)) + " kph", <1,0,0>, 1);        current = new;    } }`

Awesome script, but one question. If I wanted to convert this to Miles Per Hour instead of Kilometers Per Hour, what would the script be then?
