Works pretty well for getting just about any icicle look with some tweaking of the displacement controls etc.
Could be used for:
– Quickly generating high/low poly icicles for baking (can go very detailed/high poly)
– Clusters of unique icicles baked to a highpoly or just for a tiler.
– Can pull off that frozen waterfall icicle look if you give it the right geometry, the clusters of icicles at a high enough scatter will form together in very organic ways.

todo:
-should probably have it generate ice buildup geometry on the input mesh expanding from the icicle points..
-better ground buildup options/look
