This used to be my favourite Screensaver, but there is a high chance that a sleeping Mac will never awake again, with this screensaver running, unfortunately on my MBP 13" 2011 with 10.6.8. and 10.7.3.

IF this will get resolved I am gladly coming back.

I agree with all above.

Sadly after sleep there is a potential risk freezing the entire machine.
In my case a MacPro. I just can't longer use this as a screensaver. Really too bad. It's by far the best screensaver.

This is pretty cool. But looking at proteins all day makes me want to eat a steak.

Great screensaver, but if you actually want to AID in research while you save your screen, I suggest BOINC.

great idea! but ouch, it hard crashes my 10.3.9 powerbook if run (from a screen corner) when the saver is being previewed in system preferences. Black screen, nothing responds, never wakes up.

Also, would be nice if spinning was not simply around on one axis, but multi-axis, something a little more interesting.

Another little thing i noticed was that the protein did not spin at all if i set the speed to less than 0.50.

Great idea - I really like the concept and how it looks, just needs some touch-up work i think!
