For this lamp, I used a metal sphere that can be found at most home goods/accessory stores ($15). I added the base from an old lamp, a basic light kit and an "Edison" style light bulb.
Step 1: Wire the Base.
Using a light kit from a home improvement store, I ran the electrical cord through the base and into the fixture.
Step 2: Attach the Metal Sphere.
I sandwiched the metal sphere between the base and fixture and hand tightened it together.
Step 3: Add "Edison" Style Lightbulb.
I choose this type of lightbulb from the home improvement store for its cool look both off and on.
Step 4: Find a Great Place to Use the New Lamp.
I have it in our guest bedroom.
