Following my block, Steve made this useful block for displaying just any .ric file with passing up to 5 parameters. Note that to use make your own .ric you’ll need Andreas Dreier nxtRICeditV2 editor (download here). You’ll also need to save the .ric file in the ‘LEGO MINDSTORMS NXT\engine\Pictures’ directory.

You can download it from Steve’s page here, which has some other cool blocks and many good NXT stuff.
