    Save a char by moving the fillRect call into the loop body to avoid ;

    you're right!

    I love this!

    it's also better to use rect height for the "alpha", avoids the jagged edges on the right. for(i=c.width=99;i--;)for(j=56;j--;)x.fillRect(i,j,1,(S(j*j+i/j-t*7)+C(j**5-i/j*6+t)**3)*j/99)
