This is pretty sad.

Hey all, there are things in your houses called windows.   Try looking out them; you should see something known as a "sky."  It's there all the time and free for all to enjoy.  And if you walk out what's known as a "door" you'll see it in all its glory. 

You don't need a computer program to generate it for you.  Someone else already has.  And I doubt any software could do a better job.
