the images do look nice, but i'd be careful when trying to represent a point by using a sphere, especially one that large. i think instead i'd make a planar from a nurbs circle that has a material with no specularity or reflectivity, and then also create an insert for the page with a zoom-in to where the point would be (so that way they realize a point is so infintesimally small that it doesn't have any measurements - but you're zooming in so they can see it).

otherwise they just see a shiny glowing blue sphere, which is what i thought you were showing us until i read the text below it.
