I just noticed the new features in SP13 and they seem interesting but they are not much use without proper help and preferably tutorial.
The help only lists them in reference which is the same as can be seen on UI so it does not help.
Switch seems pretty self-explanatory and Normal to Color also, though where it is needed I have no idea. Normal visualization is already in shading modes so it cannot be for visualization only so I'm lost

But the node that sounds most interesting is totally mystery, as far as I know there is (sadly) no curve geometry in Clarisse so how to use the Curve Utility and what it does and where it is needed?
Please explain preferably with examples

Thank you!
