CBSE (CMC) Ribbons, update.

Ribbons is a nice GUI program to create stunning images of proteins, DNA, RNA and sugars.
It is very powerful and relatively user-friendly. I blogged about it a while back and lost track of the website where it can be found. I just dove around in the interwebs and I found this website:

Academic licenses are free but comercial have a cost. As always if you use it, register and cite it.
