Experimenting with GeoGebra sliders and trace.
Just hit the play button to begin the animation (NOTE: You MUST check "trace" to see the animation, it helps if you uncheck "paths"). Use the refresh icon on the top right of the applet to clear the traces. Be sure to check/uncheck the "trace" and "paths" to see what they do. Double-click on the applet to load and save a copy. Colors are what they seem, they identify a closed path/walk. Use the "coloroffset" to cycle through the other colors.
