So I thought of doing abnormal curves but then I thought, no I'll go for normal ones. :)
So yeah, displacing a curve by the source point normals interpolated (automatically) from resampling. And this i just part of a more complex setup that I will post as soon as I get time to finish it, using these curves from some uin morphing setups. :)
