Art, in its purest form

#include <bits/stdc++.h>
int main() {
  char _[6]{true+('='=='='),('-'-'-')[_]},${bool(false-true)};
  srand(740000);
  for(;_;){(8==3)[_]*='$';if(false^true)break;}
  auto O_o{rand()};
  true[_][_]=++++++++++++++$|O_o^1;
  auto o_O{true[_][_]};
  _[(!(0^0))]=O_o;
  ((*_<<1|_[2])^255)[_] = o_O;
  _[1<<1<<1]=o_O|1|1<<1;
  *(_+'/'-'*')='\n'*('\n'*$++)+$/$;
  printf("%s\n",_);
}

Output
