Disks

Displays disks rolling in the rows of the display. Disks can have 2 different velocities and colors. Disks reflect at the left/right border and when hitting a disk of the same color. Running into a disk of mismatching color makes both disks drop to new rows depending on their velocity.

Options

• -x: use service point display emulator
• -s: send to service point display
• -23: time in seconds to run

Examples

disks -x -s

Tunnel

Display a fly through a tunnel animation.

Options

• -x: use service point display emulator
• -s: send to service point display
• -23: time in seconds to run

Examples

tunnel -x -s

Eyes

An animation of 2 eyes, blinking and looking into different directions

The default storyline is:

• look straight for some time
• look around, discover something iteresting on the right
• think about it, thing even harder
• feel dizzy from thinking, fall asleep

Options

• -x: use service point display emulator
• -s: send to service point display
• -p...: provide a playbook as string; chars mean:
  • . / _: wait short / long
  • x / X: move eyes straight slow / fast
  • l / l: move eyes left down slow / fast
  • r / R: move eyes right down slow / fast
  • t / T: move eyes up thinking slow / fast
  • h / H: move eyes up thinking hard slow / fast
  • d / D: move eyes dizzy slow / fast
  • s: eyes fall asleep very slow
• -23: number of times the playbook is played

Examples

eyes -s -x -p_ # look straight only

Airport

Emulator for a Split-flap display like the ones that used to be in airports.

Reads from standard in, a blank line starts the display to update.

Options

• -x: use service point display emulator
• -s: send to service point display
• -23: time in seconds to run

Examples

friedrichstrasse | airport -x -s

Roll

Read from stdin up to an empty line, display 56x20 charackers, repeat. Charakters are updated with an roling effect

Options

• -x: use service point display emulator
• -s: send to service point display
• -23: time in seconds to run

Examples

friedrichstrasse | roll -x -s
