 Oh yes :) ! I´m aiming at SIGGRAPH 2011 , perhaps is too high goal for me
but I think I´m ready to take the chance :)

 The good thing about the algorithm I´m developing is that it is
relatively independent from the subdivision scheme used, so the simpler,
the faster to calculate and for several architectural decitions I´m
enforcing triangles only. (you will understand why sculptris use
triangles only too ;) ) so I end up using Loop subdivision scheme.

 Definately Centriodal Voronoi Tessellations are an appealing
remeshing/relaxation algorithm and I have being tempted to put my hands
on it, but I don´t know the status of the quad remeshing GSOC and I don´t
want to overlap with that cool project, perhaps in the future, when
Unlimited Clay is fleshed out I could extend its relaxation scheme to
include it, it will be fun ;)

 Thanks for your advices ... I wish you the best of luck too.
