He's very enthusiastic about sharing his tricks too. I spent the day hanging out with him at Troopers in March and we spent a lot of time discussing the structure of PDFs.

He's the one behind the file tricks in the journal of POC||GTFO - http://www.exploit-db.com/wp-content/themes/exploit/docs/poc...

In fact, he set a fun challenge - can you produce a PDF file that is different every time it's opened? e.g. a bingo card generator.

The back of his business cards have cut down introductions versions of his posters, so everyone takes something away from meeting him. It's fun watching people decide which one they want.
