IMAGE DESCRIPTION: 

I wanted the theme to be more subtle - it's supposed to represent a
juxtaposition between being free and being confined.  The ship is sailing in a
bathtub, but the tiles are also like a sky... like the Earth - you can travel
across it's surface but you can't break into space.  It's not fantasy/mystical
in the more popular swords & dragons sense, but I believe that it still fits
the topic.


DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 

This is my first IRTC entry, and actually my first serious scene, and well... I
kind of left it to the last minute.  I compiled MegaPov on FreeBSD myself and
for some reason it kept seg faulting when I made the slightest changes, like
ambient 0.001 to ambient 0.0.  At first an area_light also made it seg fault
but a few minutes ago I tried compiling it with an area_light and it worked. 
Great.  Then I checked the IRTC page and there were 9 minutes left.  The scene
you see is not exactly the scene that can be rendered from the scene file, but
I guess it will have to do.
The tiles were my biggest challenge.  At first I tried making them reflective,
so they would reflect the sky... then I tried image_mapping a sky on to them. 
Finally, I used the simpliest solution:  Making it transparent.  I couldn't
believe I didn't think of that.
The body of the ship, sails and tap were all modelled in Hamapatch.  The texture
of the grout on the tiles is granite, as is the side of the ship.  I'm most
proud of the bamboo texture found on the sticks supporting the sails.
The bathtub is a csg of a big box, 3 cylinders, 2 half-spheres and a smaller
box.  The edge of the bathtub is composed of half-cylinders and half-torii,
scaled on the Y axis.
I worked on the sky a lot, and finally came up with the results you see.
I didn't include the scene source because I'm out of time!
