powder packing density!!!

Thought this may be of interest to some,

It has just been published that M& M sweets pack together more densely then
perfect spheres when randomly jumbled in a container.
It was also discovered that by stretching the M&M shape (so elliptical,
like an almond) in computer simulations, a packing density approaching the
packing fraction of 0.74 was achieved.

This seems to me to be important to anyone involved with producing
components from powders, be it by conventional methods or by rapid
manufacturing techniques. Does anyone have any comments/thoughts on this

P.S. I have just finished a PhD based on SLS and am currently looking for
employment. Anyone who has any vacancies arising in the near future please
contact me at the email address above.
