comment Driving a common cathode 8x8 RGB LED Matrix with PWM
@joh Ok, right. For some reason, I wasn't able to see the datasheet, from Chrome. Now I've tried from IE9, and I saw it.

comment Can a dynamic circuit extract all energy from an ultra capacitor?
@Anthony It is not expensive, but not easy, either. You should not do it on a breadboard, and the PCB layout, being it not difficult, is not trivial for someone new to electronics. I don't know what's your experience doing PCBs. // If you can buy a "step-up" or "step-up/down" dc-dc converter already done, it will be best. I can't recommend any specific one, because I don't know the specs.

comment Driving a common cathode 8x8 RGB LED Matrix with PWM
You have 192 anode terminals and one cathode terminal. How would you excite 192 anodes with 24 current-sourcing nodes, keeping all LEDs independent?

@Kortuk He would need 8x8x3=192 of them :)

comment In terms of protection, how does this automotive power supply circuit look?
Don't we need to see the second page of the schematic? It says "Sheet 1/2". // Some labels, like VIN, and BPOS, only appear once. Where do they go? // How much is VCLEAN for you?

"Is there any way to use a current-sinking LED driver to drive a common-cathode LED matrix?" No.
