What is the difference in golf putter designs?

QUESTION: I'm new to golf (so don't laugh please :P), but when purchasing a putter I noticed that some were designed like a traditional putter (flat, rectangular) but some had differently designed and 'fancy' club heads... what is the difference? Is there an advantage based on the design? ANSWER:

The differences in clubs is mostly just looks but there some things that separate an OK putter from a great one. -The putter feels balanced in your hand. -The putter's shaft is made from a superior and flexible material -The directional line painted on the putter's top is clear to your eye and is easy to follow as the swing motion activates. These markings help you to see the line you are drawing as you swing and follow through after you hit it. - the shape of the putter head seems to you to help you keep it straight through the swing. - advertised to have a wide "sweet spot" Now all of that said, the most important thing is not the putter. It's you and your ability to read the ground surface for what will affect the ball as it rolls to the hole. The speed that you hit it is also very important and is learned with practice. This will come form experience and is an art within the game of golf.
