Winforms custom control - Hierarchy mapper

Winforms custom control - Hierarchy mapper

"Last night I took someone up on a dare and whipped up a quick-n'dirty winforms control which allows graphically mapping connections between nodes in different hierarchial views (represented by treeviews). The connections are created by dragging nodes from one side to the other, they are selectable (just click on a line), they support context menus. It is similar to the BizTalk Mapper UI and other graphical XSL generation tools ."

Pretty cool example. I know I've needed something like this in the past...
