- Easy.
- With effort.
- Barely.
- No, it is unintelligible.

Due to incessant spammage on the forums, I wrote an improved CAPTCHA script using Panda3D. It might take some tweaking to make it work on a webhost so I’m releasing it under a zlib-style license.
It requires the following truetype fonts:
Barred Out.ttf
Schizm.ttf
Scratch my back.ttf
SF Wasabi.ttf
Shattered.ttf
Spotted Fever.ttf
Staccatissmo.ttf
They are available for free on the internet and should be easy to find.
Also the environment.egg file (at least the last time I checked) has some improperly applied textures. Change
<Texture> Tex975 {
"maps/envir-mountain2.png"
<Scalar> format { rgba }
<Scalar> wrapu { repeat }
<Scalar> wrapv { repeat }
<Scalar> minfilter { linear_mipmap_linear }
<Scalar> magfilter { linear }
}To
<Texture> Tex975 {
"maps/envir-mountain2.png"
<Scalar> format { rgba }
<Scalar> wrapu { CLAMP }
<Scalar> wrapv { CLAMP }
<Scalar> minfilter { linear_mipmap_linear }
<Scalar> magfilter { linear }
}Same for “maps/envir-mountain1.png”, “maps/envir-groundcover1.png”, “maps/envir-reeds.png”, and “maps/envir-bamboo.png”. Things will look much better without the stray lines.

Tell me what you think! 
That’s absurd. Graphics rendering and pattern recognition are two completely different things. That spammers may find the code is totally irrelevant. According to
