Even though this design is not too practical, I still like the idea: Tilt the clock to switch daylight savings time on and off. Without having to change the hand. After reading the comments at Engadget, one additional drawback (apart from the missing hour numbers) became clear: the clock changes 1 hour plus/minus 5 minutes, not 1 hour when tilted.
