Heres a new way to find what you're looking for - Yahoo! Answers
Instead of shift register, use 3 to 8 decoder.. In moving display columns are scanned not rows. Select a particular column from decoder and apply value to row to light a pattern. Follow this for all 8 columns to complete a letter. Do this repeatedly and should be speedy.
