Right now all you can do is place nodes. Can't connect them yet, or do anything else. Just draw nodes over and over. Soon (hopefully today) I will have it so the starting node can be connected with the ending node to create a polygon. I know, it's not much, but it's something to hold me over until I can get a new video card so I can continue working on Lazteroids 2 (*cough*playing games*cough*).
Here's the executable if you really want it, though, i'm sure you don't as it's rather quite useless. Spacebar places nodes, backspace deletes the last node, and escape erased all nodes.
