One of the tools I was playing with in XSI last night was a spine deformer. It's pretty cool in that you can take any polygon or nurbs surface and draw a line on it then use the spine deformer to move the surface around as you translate, rotate or scale the curve. Or you can use proportional modeling on the curve to just move parts of the curve with a falloff. It's not exactly like the Silo method but its somewhat similar. And it's really fun to work with, which is my favorite part about the whole thing.
Silo looks like a fun program to model with. Kinda' like ZBrush in some respects.
