Here are a few art clock ideas I've had:
R R R R R R R R R R R R
G G G G G G G G G G G G
Y Y Y Y
or
R R R R G G G G
R R R R G G G G
R R R R G G G G
Y Y Y Y
Twelve red LEDs at the top light up to show the hour.
Twelve green LEDs below that light to show the five-minute interval.
Four yellow LEDs below that show the minute.
Clocks with mechanical displays are also interesting. Two I'd like to see:
Metal ring with a hub in the middle. Time is displayed by short and long lengths of wire, with a ball-bearing at the end, which rotate around like regular clock hands, with no visible support. There would be electromagnets in the ring to step the "hands" around.
Flat black surface, with Roman numeral markings in a circle. Two ball bearings are stuck to it with no visible means of support, and step around to indicate the time. Electromagnets behind the surface would be driven sequentially.
