Nick, I'm definitely interested in your OpenLCD project. I started playing around with a 16x2 display last night, starting with the 8 bit interface and then going to 4, and then this morning I was thinking that it should be simple (and cheap) to delegate control to another Arduino chip. Lo and behold, I stumble upon this thread! ;D So, please keep us posted on your progress! I'd love to see some code in the SF SVN repository... (hint, hint! ;))
