Hi, your readers might be interested to know that texture nodes have been committed to SVN and will be in the next release.
It's a new node type that lets you create your own procedural textures. Supported features include animation, infinite resolution, and multiple output channels.
- TextureNode manual (work in progress)
- BlenderDev/TextureNodes page
- Completely, utterly, totally insane application of TextureNodes (which led to a few cries of disbelief in the BlenderFoundation chat channel earlier today ;-)
