A few years ago, someone (I think it was korli, but himself got it from scottmc or something like that) gave me a PicoLCD 20x2 module (http://www.mini-box.com/picoLCD-20x2-OEM). Basically this is a small LCD display, 2 lines of 20 characters.
Today I finally wrote a little application allowing to use it under Haiku (well, actually, I found someone who wrote an easily portable driver, and added some functionality around it).
The LCD is now used to show CPU usage bars, as the blinkenlights did on BeOS. It works with up to 6 CPU cores (the best I could do with only 2 lines of text and 8 re-definable characters).
The sourcecode is there: https://github.com/pulkomandy/picolcd
No pictures, because this is only fun to watch in realtime.
