Here's something I put together last couple of days. It's a graphic of toratope notation, along with the equation, and some other stuff.

For a wythoffpolytope, it's a matter of replacing o, x with oo, xm, and then put &#mt at the end. This is of course, to suppose a point expanding into a polytope as a pyramid peak in one direction, and from inside this pyramid peak, a second of the dual expanding. If ye look at the cube, you can colour three faces around a point red, and the opposite three blue. This gives an expansion of triangles from the red vertex, until the triangles meet the blue bits and the section becomes a hexagon (truncated triangle), and then a point (rectified triangle).
