Improvements for the ubiquitous alarm clock

LED animations are nice, but they shouldn't stand in the way of functionality.  The DOTKLOK has very long time transition animations.  This will get annoying real soon.

Some of the clocks show the time up to second resolution.  For a bed side alarm clock, I don't see a point in doing that.  Besides, how accurate is the clock anyway?  If the clock is not regularly synced to some time source, the shown seconds will be incorrect.  Second resolution is useful in timers (for cooking etc.), but an alarm clock is not a timer.

Nice animation, (too) big LED array, too bright, blue color will keep you awake

Nice clock, but without a manual, you can't properly operate it.  Sometimes digits are green and sometimes red.

The idea of the arcade buttons is good, but the menu navigation is quite unusual.  The black button cycles through the menu items of the top hierarchy level.  The red button is used to go from top hierarchy to the level second level.  Then it cycles through the menu items of that second level.  The white button finally is used to change user settings.  As there are only three buttons, you can only cycle in one direction through the items.  For setting the year or the minutes of the hour, that's quite annoying.  A fourth button would have made menu navigation a lot more intuitive: up, down, select & back.

See how long it takes and how many key presses are needed to set it all up?
