It was only a couple of weeks ago we had Warren Delano presenting on new 
PyMol developments at our eCheminfo community of practice program at 
Bryn Mawr:

What a shock and sadness to see this news of his sudden death at home in 
my email box today. Our thoughts are with his family and friends.

Sorry to lose you so young Warren.  Life is just not very fair.  RIP but 
let your work live on.

As a scientific community let's make sure that Warren's work continues 
and is built upon. He created something useful for others to benefit 
from, and the Open Source model allows that to continue
