My Hobby: I make lots of Excel tables. I mean a LOT. Seriously. I've got tables to show loan schedules, a table of a collection, a table of collections of collections, a puzzle generating spreadsheet, a puzzle
solving spreadsheet, I've even got an Excel spreadsheet that encrypts and decrypts messages using monoalphabetic ciphers, Viginere ciphers and, wait for it, the Enigma cipher. I've made an entirely working Enigma machine in Excel. Anyone think that's sad? Well how about logic problems? I love logic and so I'm often interested to do puzzles such as Sudoku and Kakuro but I also like more abstract ones. I'm currently in the middle of Euclid's "The Elements", one of the most incredible, logical and amazingly dry books on geometry ever published. Anyone wish to join me?
Your Hobby: I love it. I loved the picture and I'm going to send it to all my friends who profess their want for a Mac. That is also one of my favourite XKCD comics.
