\ convert to binary 
: f 0 >r a:new swap ( nip >bin s:len r> n:max >r a:push ) a:each drop ;

\ pad binary number with zero
: f1 a:new swap ( nip '0 G:c# r@ G:#> s:fmt a:push ) a:each drop rdrop ;

\ replace every 0 with space
: f2 a:new swap ( nip /0/ " " s:replace! a:push ) a:each drop ;

\ replace every 1 with * and print each line of bricks
: f3 ( nip /1/ "*" s:replace! . cr ) a:each drop ;

These words must be invoked in sequence (see example)
