Broken Telephone #1 calls for Art, the even numbered BT's will be Music

This time the theme prompt is "Braving the Unknown"

We are to submit one graphical art piece.

This does have some polygon primitives and 3D shapes because it was a manual process with Paint 3D.  The intent here is a remote successor to Marble Madness maybe late 1990's in an alternate timeline.  Braving the unknown = the playfield is mostly black so you can't see whats going on.
