[time-nuts] Time shown as two horizontal bars

Looking for a long, thin horizontal clock display for use above or below
a flat screen TV.

Tried searching for "bar clock" and got a lot of useless hits.

What I'd like is a display that is about half an inch (12 mm) high by
12-18 inches long (30-50 cm) that is just two rows of 60 or 120 leds.
One row is labeled 0 to 59 (or 60) and the other is labeled 0 to 12. The
display does not stay at 12 or 60 but jumps back to zero. Power line
frequency is an adequate reference, as long as it always has the same
86,400 seconds per day, except for added leap seconds. There should not
be a clock frequency adjustment.

60 seconds worth of line cycles bumps the minute bar (30 if it has 120
leds), and 5 minutes bumps the hour bar (150 seconds for 120 leds).

The clock is set (after startup and power outages) by four buttons on
the back - minutes, increment, decrement, hours.

Have any of you connoisseurs of time seen such a clock? How about a bar
of leds that could be used to make a clock?

P.S. Currently re-reading Terry Pratchett's "Thief of Time" - a whole
new way to look at time in a funny and perceptive story.
