A rack mounted LED array of wikipedia:blinkenlights, 1RU, which emulates wikipedia:KITTs scanner by visual, but is similar to the wikipedia:BeBox's blinkenlights for function.

What can it display?
- Status monitors
- KITT Scanner
- Error displays
- Guru Meditation error
- BSOD
- Screensavers (may require multiple in sync)
- Conways game of life
- Matrix
- PONG
- other
- snow crash visual
- heartbeat (slow speed)
- screensaver (medium)
- crash indicator(fast!)
- snow crash visual
Extending the basic idea
The basic display should be standalone, but racks tend to be in servers, stacked... so there should be a way to synchronise multiple rKITTs for easier overall displays. For eg:
- KITT scanner is at the left at the start of every minute, so ALL displays sync up, and it's easier to see which is fastest...
- say: scanner scans (a full left-right-left cycle) at X scans per 10 seconds, and only updates the speed every 10th second. That way every 10 seconds it is back to the left. 5 scans/10seconds = default. Integer scan count/10 seconds.
- most screensavers (esp Matrix) will improve across multiple lines, so a basic protocol to transmit data "down" and "up" (left/right too?)
limitations
- how many LEDs can be lit at once as powered by USB?

- how many LEDs can be controlled at what speed by PIC controllers? (PIC bandwidth?)
- how much space (depth) to build this. The idea is it can sit in FRONT of a machine in a rack cabinet
- remember to consider rKITT heatsink issues, and server case airflow issues!
