What do you guys think??? Pretty cool huh!!! It's very easy to make. Create two cylinders, one smaller than the other. Put the smaller cylinder inside the larger one and create a boolean difference. Now create a sphere. Size it so it will now fit inside the hollow cylinder you created with the boolean differnce. Let part of the sphere show out the top of the cylinder like in the image. Your done!!! Now what you can do is edit the material on the sphere so it is glowing. Change the color maps and functions to get different effects like in the images shown. Enjoy!!! Jim
