Wow guys! Thank you so much. I really appreciate it!
Graynomad:
But you don't need MISO because you are only talking one way.
oh.. that right! Thanks!
But I have some more questions guys...
It's alright.. I just want to understand how this "business" works. I will get a Attiny with more pins if needed. Thanks anyway!
How exactly to load it? $)
Lakes:
You can do it with an ATtiny, but you have to charlieplex the LED`s.

WOW! LOVE YOUR LINKS, THANKS!
really helpful.
Graynomad:
mixania, just use a shift register and save yourself a lot of pain
Hmmm.. What about it? How it works? ]
NiรฑoScript:
add 8 16bit I2C GPIO expanders, and use charlieplexing
there you go, direct control for 16256 LEDs, using only two pins of your Arduinoenough for a 25 x 25 x 25 LED cube
Wow! Man thats crazy! maybee some day.. $) 8)
