Was thinking about how to generate some randomization to drawing in GeoGebra and this is what I got! Drag the point to draw, the colored points will orbit around it. Reset brings the points back close and distributes them around. Erase does what you'd think. Trace lets you turn the trace on and off. The lone checkbox hides stuff to make your pictures pretty.
