Rokenbok Rokenbok is an advanced, radio-controlled environment of building, sharing and learning. While not quite particle physics or astronavigation, it is both fun and flexible. This latest construct occurred in my lesser stairwell. The bottom of the stained-glass window (another of my hobbies) is about 9 feet. The top of the window is at 12 feet. The ceiling is at 14 feet. The tallest structure is both the base structure as well as an elevator shaft for the radio-controlled elevator. The elevator and roadway allows radio-controlled vehicles to get from downstairs to upstairs and vice versa. The structure between the elevator shaft and the opposite wall is merely seismic support as I live in earthquake country. There are more pictures to come, as this is only the beginning of this construction effort.
