Here's a sketch I cobbled together for displaying greyscale images. Any comments / suggestions will be greatly appreciated.

 Sketch concept: rotating picture frame for Peggy 2/2LE
 
 Sketch was cobbled together from the Peggy2_16level demo included with the
 Peggy2 Library. BMP2PEG was used to create the tables for the bmp-bitmap
 data. The Arduino Flash Library is used to load the tables into flash
 memory to save space / load more pictures. All I have done is taken
 pieces of data, placed them in an editor, and shook my laptop like an
 etch-a-sketch and hoped for the best. I have still a long way to go with
 this.
 
 
 Thank you Messrs. Oskay, Hart, and Delp for your hard and excellent work.
 I would be the onwner of a LED-enhanced paperwork without you.
 
 
 Here are the specifics for those who made this all possible:
 Peggy 2LE board designed by Evil Mad Scientist.
 (aligning the LEDs into a military-precision formation worked wonders for my OCD
 and
 Peggy2_16level.pde - Simple example code for Peggy 2.0, using the Peggy2 library, version 0.2.
 Generate four frame buffers and switch between them *fast* to make gray scale.

 Flash Arduino Library
 Loads data into flash memory instead of SRAM
            and

 Image tables made by BMP2PEG.
 Converts bmp images into 16-bit data tables.
