Just repeatedly serial input the pattern (data, clock) and wait till the pattern is complete before latching it. Then blank (output disable) and repeat the pattern for the next digit. You might have to play around with the refresh rate to avoid flickering. As per the brightness of the LED, the single external resistor can control the brightness for the entire series of LEDs. It works with mine, and if it still doesn't work, adjust the duty cycle. I'm not sure if you can do the animation in Photoshop, but I've been doing some of mine with Macromedia Fireworks. Works like a charm -- avoids resaving the file multiple times too :) I’ve had no problems lighting several LEDs at the same time.
