I'm curious what kind of software :

is capable to create 3D animation ?
There is a link: http://www.elcojacobs.com/shiftpwm/  , it says limit 768, w/ 75 fps. So you should be o'k with 60 fps.

The shift register thing isn't really that helpful for me, I don't think... unless I'm missing the idea. I need complete simultaneous control over everything. I've pretty much decided to just multiplex out the signal from the USB controller, no arduino.

Also... I haven't written it yet :3
Most of that comes after it's built.

I wasn't saying I expected 60 fps and 64 shades, I was saying those were my ideals. I expect/plan to get worse performance (that is, lower frame rate and shade count) if I use an arduino.

I don't understand what you're saying in some places.. why you mentioned bytes and bit stuffing where you did, 'read not', and both of the last two lines. Also not sure how you got 600,000 bps instead of 360,000, or 75,000 instead of 60,000. Could you explain? Remember I don't know much about the arduino. Where would this bit stuffing come in? Why does the baud have to be so much higher than the bit rate for a simple multiplexer?

Edit:
And how many/what pins would you use to get the highest total bit rate possible?

I want to make a 10x10x10 single color LED cube, with a good, very smooth frame rate and the most detailed brightness control I can get. I've never used an arduino before (or played with electronics much) and was wondering if there was any chance of it being able to keep up with that. What is the highest overall throughput you can get with whatever arduino and set of pins (and circumvention of arduino code functions) is best? Can the mega manage much more or do those extra pins make them slower?

I'll be running animation and audio visualization/audio processing software from my laptop as I'm pretty sure it can't do all that by itself. Eventually I'd like to find something that can, without any computer. In an ideal world, a minimum of something like 60 frames per second and 64 brightness levels. Maybe I should just send serial directly from a USB chip into the multiplexer? Reprogram it to remove any signal management? I can't imagine that not being fast enough....
