I'm seeing the 3D plot of the points in your list a. That's with
Mathematica 8.0.1 under Windows XP.
Did you perhaps evaluate the expression for a in one session then in
another session evaluate the ListPointPlot3D expression but forget to
evaluate the expression creating a? (Mathematica doesn't remember such
assignments from one session to another.)
If that's not the source of the problem, what version of Mathematica are
you using and on what platform.
