 That said, using spaces and '#' characters takes a bit more work.  One approach would be:
-<lang j>   N=:2
+<lang j>
-   ' #'{~(#:7 5 7) ,/@(1 3 ,/"2@|: */)^:N ,.1
+   scarp=:{{' #'{~(#:7 5 7) ,/@(1 3 ,/"2@|: */)^:y ,.1}}
+   scarp 2

 Here, what we are doing is forming a tensor product of our #:7 5 7 boolean array with our argument and then collapsing two of the dimensions so they line up right. Our starting argument is the 1 by 1 array with the value 1. Once we have repeated this process enough times, we select spaces for our zeros and pound signs for our 1s.
