As I'm finalizing the CSS conversion of the Math design, I need your help on the images for the 404/Captcha/error pages. You can see the ones I used on the other StackExhange sites.
The idea is to keep it related to the site's topic, but also a bit light-hearted. For example, for Gaming site: Captcha
For Cooking site:
You can append /error, /404, /captcha to see the images from the other newly graduated Stack Exchange sites.
So, what should I use for the Math site? I think it'd be clever to use some in-joke type of math comic strips, assuming they're ok for us to use copy-right wise.
