Spline blur node in Substance Designer

Hey everyone 🙂 I hope you are having a beautiful day!
This is a proof of concept for a spline driven blur node. This is an obvious thing to do given the awesome spline tools we have in SD.
In simple terms we need to color the spline path with its velocity vectors. We then spread these vectors with the distance node in the 2d space. We then do chained directional warps informed by this vector field.
This can be pushed even more to take as input multiple splines or splines on splines.
