The Herman clock is designed for the bedroom and other rooms that shifts between daylight and darkness. The dial of the clock paints a graphic picture of black and white lines, dividing the display in 12 zones, one for each hours of the day. The white lines are made of a fluorescent material that is "charged" by daylight and creates a glowing display in the dark. A major influence has been optical illusions like the Hermann grid, where a visual distortion caused by black and white lines makes you see patterns that are not there.
The deep frame of the clock draws your focus towards the display and acts as a shade for the florescent light at night time. A solid cast iron body gives the clock a unique character that resembles a lamp as much as it does a clock.
