Designed by Bert, Aug 1999

Recipe:

Using The Gimp,
0. Start a New canvas of 100x100
1. draw a simple shape by hand with the brush tool,
2. Select-by-color with fuzziness set to about 80
3. Copy the selection
4. create a new layer, and Paste onto that
5. Move the selection a bit to the top left
6. go back to the background layer and Desaturate
7. if necessary, Brighten the background layer a bit
8. Save to gzip format (.xcf.gz)
9. Flatten and save to PNG (.png)

For the 48x48 images:
pngtopnm foo.png | pnmscale -height 48 | pnmtopng -gamma 1 >foo-48.png

(The Gimp generates gamma=1.0) 

Legend:
- *.xcf.gz are 100x100 Gimp images
- *.png are 100x100 PNG images exported from The Gimp
- *-48.png are 48x48 PNG images reduced with pnmscale
- r-* = dark red foreground
- b-* = light blue foreground
