Hmmm...
Your right about the marble.
I'll move all of the keys to make a space for more of a reaction of that.
Kind of a pain but I want to make something nice.

The brick was done with ridged body simulation,
redoing it will take some time but I think I can make it fall faster although I need to cut down on the keys significantly then add them back.

The camera will be fixed,the render shows where the camera will be,I'm going to keep ti fixed although I have this master plan of adding to the scene explaining the marble and brick,
however I'm going to focus on finishing it and maybe adding on to it since I coudl seamlessly add the explanation to the scene.

Thanks for the input

I'll put some time into it today and try to fix some of these issues.
