Homemade butter

I think it would be totally cool to make my own butter, but I'm not sure that it'll be cheaper to do that in the end. Still, it's an interesting project to keep in mind should I ever get the urge. Basically, you just beat some cream and salt in a stand mixer past the stage where it looks like lumpy eggs and buttermilk liquid starts forming. Strain out the buttermilk (you can make yummy pancakes with it!) and fill bowl of butter with cold water and start mushing the butter into a ball of butter. Keep mushing the ball until water runs clear, then wrap it up for storage!
