Distance

This is the craziest thing I've seen in a long time. Youhave to get out of your seat and walk away fromyour computer. People may think you're crazy.But it's well worth it. When you look at this picture in acloser look you see its Albert Einstein.But if you stand 15 feet away, It will become Marilyn Monroe. Give a try
