App 2.36.0: Overview style Grid, after the Tron films
Neon lines on black over a perspective grid floor that moves with the speed; the battery as a light wall, power on a disc whose inner ring turns with it, and the last two minutes of power as a light-cycle trail of right angles (the Cockpit's PowerTrace, now in ClusterValues). Cyan, or the accent colour; in cyan the app turns cyan too. In THEMES.md with two screenshots. Emulator only; not tried on the car.

/**
|
||||
* The Grid Overview style, after the neon world of the Tron films: glowing lines on black, a
|
||||
* perspective grid floor that runs towards you with the speed, and shapes with cut corners.
|
||||
*
|
||||
* Centre: the speed, large and thin. Left: the battery as a segmented light wall standing on
|
||||
* the floor, with the charge and range beside it. Right: power on a disc — the ring lights from
|
||||
* the top, clockwise while drawing and anticlockwise while regenerating, and its inner ring
|
||||
* turns with the power. On the floor, the last two minutes of power as a light-cycle trail,
|
||||
* which only ever turns at right angles. P R N D as tiles on top, the clock top right, and a
|
||||
* row of read-outs along the bottom. Unread values show "—", light nothing and leave gaps in
|
||||
* the trail; the floor stands still when the speed is unread.
|
||||
*
|
||||
* Two palettes: the original cyan, or the chosen accent colour ({@link #setAccentPalette}). A
|
||||
* low battery is orange in the original (the films' other side) and white in the accent one,
|
||||
* so it never looks like the accent itself. The floor and the disc animate (about 30 frames a
|
||||
* second) only while the car moves and the view is on screen.
