Bliptronic LEDs with SPI

I'm using some of the 20mm bliptronic pixels.
I am struggling to control the LEDs with their sample code.

I would LOVE to use SPI to control these things. However,
they require an external clock. Is there any way to configure the hardware SPI to put out a continuous clock output? Or am I forced to use the software SPI interface that Bliptronic wrote?

Thanks in advance for any support!

p.s.
Bliptronic is kind of stingy in that they don't provide a real data sheet.
(Shiftbrites are far better documented but i went with the Bliptronics because I needed 35 of them and could save some money... and the bliptronic ones are waterproof) Not to mention Macegr is awesome for shiftbrite support!

Haha Fair enough... :stuck_out_tongue:

I have their code working now. It was a few minor issues with modifications that I have made.
So technically, I can use their code for what I am doing.

I just think that hardware SPI would be a good exercise and it would make for much cleaner and manageable code.

So my question is as follows:
Can you configure the Arduino SPI to have a continuous clock. That is, so that the clock is always pulsing weather or not the data is coming out? OR is there a way to write the SPI code so that it is always sending out my array data?
