I love the way POV-Ray allows me to quickly generate cool graphics. 
Here's the logo for a programming language I'm developing called PigeonTalk.

To produce this image, I just brought up the image of a pigeon and 
captured the coordinates of various points along the profile.  I then 
used a sweep spline and added a few more control points to create the 
ellipse around it and added a sky background. Pretty easy overall and I 
think the result isn't bad.  There's one small anomaly I can see, but 
otherwise it's good.

Logos are one of my favorite things to do with POV-Ray and that's a good one!
I've been using sphere_sweeps lately too and they're a lot of fun but a little
tricky in some regards. Looking at your logo makes me wonder if it would be
possible to make the beak pointed by reducing the radius in that area.

Kind regards,
Dave Blandston

Nice!

I happen to be working on something similar at the moment, but my shape is made
by a rather brute-force method, not as elegant as yours: Using eval_pigment to
'trace' some high-contrast black/white artwork-- line art, really-- then using
the found white colors as position indicators and on/off switches to place LOTS
of spheres side-by-side, to look like a sinuous single object.

I like your sweep-spline approach better, as well as the fewer chosen points
along the profile, which is more efficient; I may have to 'borrow' that idea.
:-)

I was delighted when I punched in all the numbers and hit Render and it 
came up with the outline of a pigeon.  The first draft was upside down 
and too small, but that was easy to fix.  I rather liked that approach.
