3DNA?

Anybody remember it? I found an old CD I burned years ago containing all of my old setup files for a bunch of 3DNA environments. I think I'm going to install it today, and try to imagine how it would run on a modern machine. (I'll be installing it on an XP-era PC.)

 

looks great, but 3D is not my thing,

 

Hi Ensign, 3D actually happens to be my cup of tea!
I vaguely remember having seen long ago 3DNA (or something resembling it very closely), and maybe I've even downloaded it, but then for some reasons it got lost in the sands of time.
As your post is from over a month back, I guess you can tell me more now... for one thing, can you design your own environments or do you have to make do with a few ones they provide? How much can you tamper with it?
I can't wait...
