how big is 256x256

I'm looking for a big led moving message display schematic diagram or ideas. I want to use about 256x256 leds on my display and i want to make an animation on it. I want to use discret component and pic processor not expensive proicessors.
I made a little (32x32) one with pic16f84 and many eproms memory for the program for display but for this big display (256x256) i don't know if it will work because of the refresh rate. I use also 74ls595 for lines and 4017 for the columns.
what do you think about this problem?
 

moving message dispaly

just calculate, you must take a frequency of scan at last bigger than 100 times per second (per line)
if you have this speed in your hardware/software then your 'screen' dont shoud flick
