lasso style

The other day when I was watching one of Scot Drake's painting demos on youtube (see demo here), I discovered a tool in photoshop called "the lasso tool". With this tool, I can do so many things like: create a shape, repeat that shape throughout the painting, create geometric shapes, and so on. This tool is about to change my life. After looking at one of Scot drake's demos, u can see that he has mastered the use of the lasso tool to suit his needs, and only constant practice will get me there.
