Mato (a cool guy from Japan), is working on a special version of Blender 3D. In this special version you can use SVG files as textures on your 3D models. SO, since I'm a Blender user, and wanted this for ages, I'm doing some experiments.
So here's a little scene I'm working on (the models are 3D, all the colours are svg):

I'm really quite new to inkscape, though not to 3d.... if anyone wants to have a go, I can make the files available so all you'd have to do is replace the svg files in a directory, and we can rerender... Could be fun!
