Flip Clock alternatives

I appreciate the design and use it to help me with a sense of time in Europe (Dublin and Budapest). I just wish the hour hand could be opaque or translucent when it covers another city (or be inverted text: white on black). Edit: I use the clock more than ever and just recently discovered a new use: following matches at the Australian Open. I always follow the French Open, Wimbledon and the US Open but always neglected the Australian Open because the times of the matches seemed so weird. The Pole Clock has made it clear why the matches are the times they are. The Pole Clock is now part of my daily routine!... Thank you so much!
