The Wheel of Excellence is owned by a Dutch company, Wheels of Excellence. This particular model stands about 50m high and has sealed air-conditioned cabins with one VIP cabin that has a glass floor, telephone and LCD television. Yes, a telephone and television! While the glass floor may be cool, I'm not sure that I'd find a television or telephone very useful...
If you haven't yet taken a ride in the wheel, don't worry, you have until the end of the year to do so before the she moves on to her next home. :)
