 OPNS viz we also need an "up" version that uses only basis blades,
  // we use the symbolic evaluator to make it for us ..
  // this returns : ["x","y","z",".5*(x*x+y*y+z*z)-.5",".5*(x*x+y*y+z*z)+.5"] 
  var upviz = up(Element.Vector("x","y","z")).Vector;
  
  // Next we create some points
    var p1 = up(1e3-1e1), p2 = up(-1e3-1e1), p3 = up(1e2-1e1),
        p4 = up(1e1),     p5 = up(1e2),      p6 = up(-1e2),
        p7 = up(1.5e2+1e1);
        
  // We'll display a point, point-pair, line, circle and sph
