Lorrie Cranor is a professor of computer science at Carnegie Mellon University. She's an expert on computer privacy and security. To illustrate the importance of using quality passwords, she created a wordcloud of the 1,000 most common and poorly chosen passwords. Some of the more prominent ones are "12345" and "password."
Then Cranor printed out the wordcloud as fabric using Spoonflower. She used that fabric to create this dress. Cranor wore the dress while delivering a speech about computer security. That sounds like a brilliant teaching aid!
