Houdini Origami SOP

I created this SOP a while back for a project which didn't go through. Basically it lets you create simple paper folds on a grid and animate them. The idea was to create a set of nodes which would then allow me create more advanced folds but it didn't get that far.

The SOP node worked by first setting a vector for where the paper would fold and then setting the fold angle. This was done by first splitting the grid into two sections, then rotating one side and finally attaching them together. You could also bend the fold with falloff and animate all the parameters. I will definitely be coming back to this in the future.
