Is there a way to change the color of light these boxes during the course of the experiment dynamically.
<box id="box1" size="0.1,0.1,0.1" movable="true" mass="2.5">
<leds medium="leds">
<led offset=" 0, -0.05,0" anchor="origin" color="red" />
<led offset="0, 0.05,0" anchor="origin" color="red" />
<led offset=" 0.05, 0,0" anchor="origin" color="red" />
<led offset=" -0.05,0,0" anchor="origin" color="red" />
</leds>
</box>
