Scanned image of design diagrams by Mark Cerny of the arcade game Marble Madness. The "Traverse" and "Gravitational funnel" concepts were included in the game, while the "Ice block" and "Teeter totter" ones were excluded. Cerny created the designs while working at Atari Games. Atari Games and all of its properties are currently owned by Midway Games.

Text in the image:

Top left- "Traverse: A section of playfield at a tilt with a cliff beneath it. It is accessible from above and has an exit to the left (or right). The player must traverse it by always pushing the MTB up and to the left to counter gravity. The marble behind can bump the one in front off the cliff at the bottom or bump him down the traverse at high speed."

Top right- "Ice block: This is a section of differently colored playfield that acts as if it were a block of unsteady ice floating in water. If one player attempts to cross it the block will tilt and cast him off unless crosses it at its exact center (tilt is restricted to one direction) . If two players cross on opposing edges they can do so at any desired speed."

Bottom left- "Gravitational funnel: This is a depression in the playfield that resembles the gravitational well created by a black hole. Two paths close together are wildly divergent after they pass by, as the hole can swing a marble around 90 degrees quite readily."

Bottom right- "Teeter totter: A teeter-totter is placed as the only convenient means of exit from a plateau. When a marble rolls onto it the end sinks down to the lower level, trapping the following marble on the plateau. The teeter-totter then slowly returns to its initial state, having caused considerable delay."
