I really like do useless thing ;-p.

The control 

for the cube

x : increase by one the number of cube on the x axis

y : increase by one the number of cube on the y axis

Z : decrease by one the number of cube on the z axis

left arrow : turn left

Shift left arrow : translate left

space move forward.

ctrl space (because dont take shift space as specific keystroke and array dont take ctrl so i choose that): move backward.

i search during half a hour but dont find a relevant quote from pinky and the brain. sad.

What i really like Igor is, i don't need to close the morph for apply my change to the render method, i mean in addition to not recompile the whole project.
