Ok then I will lower the value from the resistor to around 180 ohm (to be in the middle of safe and bright ;)). So you are saying I can switch on all the grounds from each level (3 grounds in total) and then turn on 1 column so I get a vertical line that is lit. So I also can make a wall of LEDs just by turning on all the grounds and turning on 3 columns?
And I don't get your last sentence 
"I think Its possible to do all the other things you list, but you probably wont want to do them." Are you reffering to an easier way to make a 3x3x3 LED?
