Each number on the wheel represents a ball with a specific weight. You choose what the unit of weight will be. This wheel should rotate CW due to gravity and momentum. I can prove to you that this wheel is unbalanced. I can also prove to you that it is balanced. There is mathematics and a pattern to the numbers in order to achieve this. It's similar to an Archimedes spiral. Order out of chaos.

So the wheel is supposed to keep turning due to just the position of the weights alone? I couldn't imagine how that would work but it would be a powerful and fast wheel lol

It was designed to be a momentum wheel like you suggested. I thought at first the momentum of it may overcome gravity, but I highly doubt this would be the case. The purpose of posting it here was to inspire the idea so it could be modified into a gravity wheel somehow along with other ideas. I believe the #5 and #9 weights need to be swapped though. Using both sides of the wheel with a different pattern may have potential. The system is static as is, and probably needs to be made dynamic before it has potential as a gravity wheel.
It was based on a Magic Heterosquare, http://en.wikipedia.org/wiki/Heterosquare
Also there are Magic squares, Anti-magic squares, Magic circles, etc. Here's a link to wikipedia on the different variations of this, http://en.wikipedia.org/wiki/Category:Magic_squares

Here's two videos of angular momentum defying gravity.

Don't under-estimate the force of angular momentum.

Fascinating approach to a wheel!
On that offset wheel effect in the video. As a cyclist and mechanice, I'm all to familiar with the efect.
I've always regarded that as inertia offering resistance (dampening really) to a present force. Force happens to be gravity. Gravity always wins. Speeding up the wheel will increase the dampening effect, but never raise the wheel back up, or does it? And even if it does, how does additional input compare to lift generated?

In the second video around the 2:30 mark, the guy balances and holds the rotating wheel using one finger only and talks about his "incredible strength". Apparently it does have lift ?

Nah, you see it slowly falling. And he walks around, as the wheel wants to turn that way. Speed can reduce the falling over, not lift the wheel. We wish...

It's slowly falling because the speed is decreasing. With a constant speed, it will remain at that position. With an accelerating speed, it will lift. If speed can keep it from falling over and keep it upright, then it must be providing lift, a net upwards force. If speed provided a net downwards force, then it would fall faster than the rate of gravity. This is proof that there is a net upwards force.
A normal wheel system where it is balanced, the decreasing momentum of the rising side due to gravity works against the increasing momentum of the falling side due to gravity and the momentum is canceled, no net momentum due to newton's third law. In the previous paragraph, I already shown that there is a net force upwards.
Where is the net upwards force coming from. When allowed to rotate on both axis, the momentum is not canceled due to the net rotation on the other axis. This is due to newton's third law. This net rotation on the other axis is the force providing the net upwards force.
What is interesting, is why doesn't it provide a net downwards force or no net force instead of a net upwards force? This leads me to believe that the momentum of the mass on the falling side is increasing due to gravity more than what the momentum of the rising side is decreasing by due to gravity, thus providing a net upwards force. When forced to rotate on one axis, this upwards force is canceled due to newton's third law and gravity wins.
This is proof that angular momentum defies gravity in a wheel when allowed to rotate on two axis. Without gravity, a balanced wheel can rotate on momentum alone. A momentum wheel should be able to exceed the force of gravity. The net momentum will be the rate of acceleration of the wheel.
Edit:Constant Speed = Upward force is equal to gravity (No net momentum, Remains upright)
Accelerating Speed = Upward force is greater than gravity (A net momentum, Lifts)
De-accelerating Speed = Upward force is less than gravity (A loss in momentum, Falls)
