Sorry, haven't worked on Arduino stuff lately - got sidetracked on a GPS logger project, and one of those TI watch kits - but I've read all these posts with great interest.
Yes, if you read back to the beginning of this thread the resolution of the LCD display is mentioned - and yes I was thinking of a bitmap "backdrop" and only animating the gauge indicators. The LCD device I have, has a built-in microSD memory card with FAT file system, it's easy to load different gauge bitmaps.
