Via WebWord Usability, I discovered Bad Designs. The site features bad designs of everyday objects, such as auto ceiling lights where the front ceiling-light is push-on/push-off but the rear ceiling-light is operated by a dashboard switch.
There’s also a Bad Designs mailing list, which is sent out each time the site is updated. (Of course, WebWord also has a mailing list, which is how I found out about Bad Designs in the first place)
