LED bitmap builder

Gosh, is it ever annoying constructing column-based data statements for things like LED bitmaps and alphanumeric character representations!

Our handy utility lets you "draw" your letters, numbers, pictures, whatever, and export the results to data statements suitable for microcontrollers such as the SX, Basic Stamp, PIC, AVR, etc.

The utility lets you choose orientation of rows, columns, width of data statements, and more.

PLUS you can copy your data statements back in to the utility and it will recreate your "drawing" for more editing. What could be niftier?
