Cronotime Clock by Pio Manzu for Alessi (Originally designed 1966)
Electric Station Clock by Newgate
Optic Alarm Clock by Joe Colombus for Alessi (Originally designed 1970)
I'm after a new clock for Christmas, just a few ideas here. On the practicality front I should really get a desk clock, if I sorted my new room out I could have a walk clock, so I guess it doesn't help to look at both options.
All these beauties are available at Utility, which is "THE best design shop around", quote by me.
