Related question: Should we consider “how to visually represent…” questions on-topic?
Over on UX.stackexchange we get quite a few ;what's a good icon for / representation of' questions such as:
https://ux.stackexchange.com/questions/49970/i-need-some-help-with-a-metaphor-representing-requests
https://ux.stackexchange.com/questions/49748/how-can-i-show-a-traffic-device-modes
Now, we don't really like these questions. they're not really user experience questions, and they're probably a bit too subjective to have correct answers. However they do have a link to graphic design. So, as an experiment we're going to start migrating the good ones over to you guys.
If you hate the idea then let your mods know and we'll stop sending them over, leave an answer on this post, or just turn up in ux chat and shout at all of us there and we'll stop. However I've run it past some of the guys/gals in your chat room and they were (mostly) welcoming to the idea.
