Create image directly in front of head

In python, [x,y,z] + [a,b,c] actually gives you [x,y,z,a,b,c], so no wonder that doesn't work. The solution is actually much simpler. Since the quad is parented to the head, setPosition defaults to relative translation. In other words, you can simply say:

quad = viz.addTexQuad(parent=viz.HEAD, size=1)
quad.color(1,0,0)
quad.setPosition([0,0,10])

This places a red quad of 1x1 meter 10 meters in front of your view. Change size and position (and color/texture) as you see fit.
