Baby Tux and Baby Gnu

I originally created the Baby Tux in 2003 for my gnubiff software because I wanted to have some animation saying “you’ve got mail”. The result was a cute jumping baby tux that was made using constructive solid geometry (csg) and some macros borrowed from Rune S. Johansen and Chris Colefax. The render has been done using Povray, a great and free raytracer. Later, in 2005, I wanted to learn Blender so I tried to model the baby GNU and exported it to povray.

The Ancient Art of Go

Here are some images related to the ancient art of go. They’ve been produced using povray and solid constructive geometry. The hardest part was certainly goban feet which possess a very peculiar shape.

Some sources are available as macro files:

• goban.inc
• gostones.inc
• gobowls.inc
• kayawoodmap.inc

Gnome backgrounds

Thumbnails

Thumbnails have been created using the following script

#! /bin/bash

if [ $# -eq 0 ];then
    echo "Usage: `basename $0` filename" >&2
    exit 1
fi

density="1.5"
for file in $*; do
    if [ -e "$file" ]; then
        fullname=`basename $file`
        basename=${fullname%%.[^.]*}

        echo -n Processing $basename...
        convert ${file} \
           -size 128x128                 \
