Here is my (I think) entire collection of skies and themes for 3DNA. For simplicity I'm zipping all related items together so the files may be quite large for dial up users, if you need them in smaller chunks please let me know.
1. Static Skies
This is pretty much all the statics I made for 3DNA, hope you will enjoy them.
2. Dynamic Skies
I'm missing a couple here that I guess are gone forever now, but this should be enough to get you by. You will need the paid version of 3DNA to use these.
Here is my collection of themes I made, the last word past the underscore (ie - _castle, _villa, etc.) indicates what world it is for.
