C (gcc), 252 242 269 262 241 235235 220 bytes

I was on stack overflow for sockets in python, when this popped up, said why not? first code golf, so i'm not entirely sure if I followed the rules 100% (and if not and someone wants to steal my proverbial cookie and fix it, so be it). With 'o' and ' ', 255 245 272 265 244 238 238228 bytes. replace +48 with *79+32.

#define Q(P,R)(R>>P&1)+48
char a[12];i=0;fa[11];i=0;f(char*c){char b=c[0];a[3]=a[7]=a[11]='\n';a[5]=Qb=c[0];a[3]=a[7]='\n';a[5]=Q(0,b);a[1]=a[9]=Q(3,b);a[2]=a[8]=Q(2,b)|a[1];a[0]=a[10]=Q(1,b)|a[2];a[4]=a[6]=a[1]|(Q|a[2];a[4]=a[6]=a[1]|Q(2,b)&Q(1,b));printf;puts(a);if(i++<1){printfputs(""---\n"");f(c+1);}}

How it works:
I use a bit shift and bitwise and to find if a spot should be clear or a pip, then offset the 0 or 1 to the correct ASCII value. it messes up on 4 and 5, so they needed some fixing. actually added a few bytes. was able to remove several bytes by removing a mask and just using 1 (doh)

Special thanks to Mr. Xcoder for the 7 less bytes by removing an excess #define
Changes: removed memset -21 bytes. redid the bit logic for 6, 4, 2 to depend on 8|4&2, 8|4, 8|4|2, respectively. -6 bytes. removed extra newlines by using puts instead of printf, which is also shorter. shortened the array to 11, removing extra assignment. -15 bytes. NOW I think that's the best I can do.
