Here is a challenge I found that I thought might be fun to throw out to all you talented people. This is an unusual challenge.  See what you can come up with following the guidelines below. Deana   Alien World (Sci-If) DO: 1 - Stick with the Theme as outlined above. 2 - Make your creation without using a tutorial. 3 - Your main tube must be of Alien origin, and have lots of teeth, or multiple heads.  The more the better! 4 - Include two planets (neither of them Earth). 5 - Include a Nebula or Galaxy. 6 - Include an alien spacecraft. Do NOT: 1 - NO Earthly creatures, human or animal may be used. 2 - NO Man made objects. 3 - NO Terrestrial plant life.
