Pasting this snippet into the activity script, "hacks" in support for the rotary
not really smooth, but it works :-)

-------------------------------------------------------------------------

onRotary = function(clicks)
{
if (clicks>0)
{
for (i=0;i {
b.moveRight();
if ((i%3)==0) GUI.updateScreen();
}
}
else
{
for (i=0;i<(-clicks);i++)
{
b.moveLeft();
if ((i%3)==0) GUI.updateScreen();
}
}
}
