| Amazing Scientific Novelty (decorative gadget for your desk) 
This idea is about a magnetic ball bearing floating inside an electro-magnetic bowl. An iron bowl plugged into a wall outlet making it switch from one pole to the other as need and sensed by a simple electrical switch with a magnetic polished iron ball bearing being lifted above the bowl by magnetic forces.Since the bowl is round, making the shape of magnetic force trap the ball within the bowl. If the bowl is large enough and the ball heavy enough, the ball would constantly spin and never touch any surface and just float in mid-air never leaving the inside of the bowl. As the ball starts to stick to the bowl due to polarity change, sensors activate in areas of the bowl, pushing the ball back away from the sides of the bowl. The bowl would have many strips or areas or contact points of magnetic elecrticity sensors and each would have the ability to shift the magnetic properties in polarity as needed. The bowl shifts to the same polarity as the ball bearing within the bowl on a constant basis but in many places throughout the bowl. So many different points that change in polarity that the ball never has the chance to touch the bowl at all. A ball bearing has two polarities but, an electro magnet can have either polarity seperately switching between the two or just being one polarity all the time.Reward: Credit

| A Lighter Flat Screen TV
What about making Flat Screen TV's flatter by putting all of the unessacary components inside another box, that could be hidden somewhere, and then the TV would just be speakers, the lcd screen and the buttons, and it will have wires running to the other box that does all that other stuff or it could be wireless, either way would be good.

| Cell phone guitar tabs
Music players always like to share what they know and have! And in sharing tabs there is not always a PC near. It would be cool to have a software that can be used on cellphones exactly as the software called "guitarpro" which can also handle the same file type ".gp4".Reward: making such software woould be enough for me
