I noticed someone asking on where some knotwork used on a map border came from and that they were going to give it a go too.
I thought about it a bit and decided to try something myself.
Using POVRay I have genrated the three versions attached but they are only basic shaded shapes with normals imposed on them.
If anyone wants to use these as the starting point for something, please do. They will need further artistic work!
If I can help out by redoing the colour scheme, removing the normals or changing the lighting, or somesuch please let me know! I'm not entirely sure what format you're gonna want for something like this - or even if it helps at all in the first place.
In the mean time, I hope they are useful
