String.prototype.lastToFirst = function() {
  return this.charAt(this.length-1)
    + this.slice(0, this.length-1);
}

let str = '#---------';
do {
  console.log(str);
  str = str.lastToFirst();
} 
while (str[0] == '-');

for (let i = STEP; i <= LENGTH; i++) {
  let out = ''.padStart(LENGTH, SPHERE).split('');
  // $out ist jetzt ein array, um die ersetzung 
  // zu erleichtern
