motion path..
 

i am working on a little progect that calls for a little beam of light to go from one point to annother, i was going to make a sphere and run it on a motion path with a glow intensity, what i need to know is how to create a motion path and how to make an object run on it at a desired speed
any help is much apreciated ^^

create a curve. select the object, shift select the curve. In the animation menu, under curves, attach to curve. In the options you can set the start and stop keys for timing.
