Here's 31-year-old Canadian cyclist Matt Hunter riding his S-Works Enduro 29 bike completely parallel to the ground. It may seem impossible but that's what happens when you go around a sharp curve at very high speed. You know, physics! (and skills!)
It's not as beautiful as the Gyrofocus, but the TURN fireplace seems less likely to set your house on fire. After all, if your fireplace spins around 360 degrees, it should be well-secured and not just dangling from the ceiling.
