I wish I could make bricks like that.
I wish I could too, but my model-making programs are ef'd up. one only makes 2D stuff for some reason, and the other doesn't make the pieces scalable. you have to make the part smaller way in the back, and move it into contact with the other pieces. and that screws it up in some other direction, and you have to fix that. lather, rinse, repeat and hope you don't get it hopelessly ef'd up... I need to get new model-making programs...
