Subject: the power of ruby

Hi,
As i get better writing ruby scripts (im pretty new), I often wonder
if im not exploiting the power of the language or that i'm casting
precedural language ideas onto my ruby scripts. I have here a little C
program that would like some of you to Rubi-tize if possible, so that
i can see how some of you that really know the language use it.

[code]============================================

#include <stdio.h>
#include <stdlib.h>
int I;
/*-----------------------------*/
void dodot(int x){
    while(x>0){
        printf(" ");
        x--;
    }
    printf("*\n");
    sleep(10);
}
/*-----------------------------*/
int main(int argc, char *argv[])
{
    while(1){
       while(I<75){
           dodot(I);
           I++;
       }
       while(I>0){
           dodot(I);
           I--;
       }
    }
  return 0;
}
[/code]=============================================

Here is my unimaginitive attempt.

[code]==============================================
WIDTH=78;
def do_dot(i)
       i.times{print " "}
       puts "*";
end
loop{
       0.upto(WIDTH-1){|i|
               do_dot(i);
       }
       WIDTH.downto(1){|i|
               do_dot(i);
       }       
}
[/code]=============================================

Thanks.
