I have started the CSS conversion of the new design, since it's gotten a lot of positive feedback this time. I'm aiming to launch the site very soon!
Meanwhile, I need some ideas for the new site's 404/Captcha/Error page images. Examples from other SE sites:
Cooking site's 404:
Gaming site's CAPTCHA
(Normally for Captcha, we do a "robot" theme.)
Photography site's 404
The idea is to have these images somewhat light hearted, and reflect the theme of the site. For the new Programmers site, I will make the images hand-drawn marker style. I need your help with coming up with ideas. You can either describe a concept, or link to an existing image that has the concept you have in mind. I'll recreate it hand drawn style.
