Tesseract 4D Neon

A four-dimensional hypercube - a tesseract - drawn in glowing glass neon tubes, floating in a dark void. An outer cube and an inner cube joined at every corner, each tube with a white-hot core and a soft coloured glow, brighter where it comes nearer. At rest it glows dimmed behind the time, so the big neon digits read first.

Every hour, it turns in four dimensions

As the hour turns, the tesseract makes a full turn through the fourth dimension: the inner cube swells and passes out through the outer one while the outer folds in, the neon flaring to full brightness - then it settles back exactly where it was.

Tap to turn it

Tap the watch face and the tesseract turns for you.

Neon lettering

The time is lit in big neon digits, a white-hot tube with a coloured glow. The date glows in a neon panel at the top.

Three neon colours

• Cyan.
• Magenta.
• Amber.

The tesseract, the digits and the panels all take the colour.

Readings in neon panels

Steps, unread notifications and battery, each in a small glowing neon panel at 9, 3 and 6 o'clock, the icon above the value. Put another app's complication there and it shows that app's icon and text; set a slot to Empty and its panel goes away.

Easy on the battery

The face changes only once a minute at rest; the 4D turn plays only on a tap and on the hour. Always-on shows only the time as thin, dim neon outlines on black.
