There was once a young man who, in his youth, professed his desire to become a great writer.
When asked to define "great" he said, "I want to write stuff that the whole world will read, stuff that people will react to on a truly emotional level, stuff that will make them scream, cry, howl in pain and anger!"
He now works for Microsoft, writing error messages.
If it's there and you can see it - it's real. If it's not there and you can see it - it's virtual. If it's there and you can't see it - it's transparent. If it's not there and you can't see it - you erased it!
