Making 2D Arrays, Fast!

Hey
Im in a bit of trouble as I am making this effect using a massive 2D array. I have used Array Painter 1.1 to draw it and import it into flash. However, this programe SUCKS! I don’t know the exact size of my array and I want to shift bits round quickly and easily. Array Painter is impossible to work with and is slow and painful. Before I go of and just make my own Flash Based Array Painter (Which I dont have time for) I would like to know if anyone else has a better progame?!

I have searched loads but these kinds of random things are hard to find. So please I you know any better programes, please share them!

Thanks,
Dan
