you could use a mirror,... or mirrors. maybe build your own tower ,drill a hole (or holes) on top, or top rear of fridge( or where ever), instead of cylindrical , go square or rectangular so you have a flat surface to affix a mirror to the front facing side. Use black paint ,or any dark color, on the remanding surfaces.
If i saw a picture though, i could have a better idea of what you"re talkin bout.
For instance. Check out audgers pic. Face all, or most flat sides with a mirror. thats my idea
