I had a printout of the MIT guide to lock picking and used to try out stuff with some hand crafted "tools". I'd forgotten about Mitnick and later (probably via. Slashdot) came across his site again and saw this https://www.mitnicksecurity.com/kevin-mitnicks-famous-lockpi... which suddenly brought back the same image I had formed about him. Playful to the extent of not caring, irreverent, and curious.
Rest in Peace.
