Hello there, I've been working in a project that required the use of an hd44780 lcd. That inspired me of doing an lcd shield that only uses 3 digital pins of the arduino. Check my blog at http://arduinisses.blogspot.com for more info.

Arduino to hd44780 LCD with 2 digital pins: http://code.google.com/p/arduinoshiftreglcd/
On both counts they look great. I'll have to give this a go to minimise pin usuage - I could do with a debug LCD
