I have watched some pretty cool fluid tutorials where people show how to "pour" something into something else.

I'm wondering, has anybody ever made something flow down a surface? For example, take a plane and emit some fluid onto it and let it flow down the plane. Maybe even have an obstacle the fluid would flow around.

I can't seem to get it to work very good. I can "fill" up a container and get good results, but I can't get something like this to work.
