For a number of years, I've created posters and signage of all shapes and sizes for the non-profit community event called Penguicon.

 

In 2015 and 2016 I created feedback posters and consent posters to help attendees understand how to deal with any issues that might arise during the convention.

 

The full color posters have been extremely popular, with the convention receiving a lot of feedback via Twitter, Facebook, and the feedback form itself giving us credit.   Our consent poster was shared with positive messages by author John Scalzi and even people who had never been to our convention.

 

Both the consent poster and the feedback poster were ideas I came up with as Head of Communications.
