Today I have become older. Ho-diddly-hum.

It seems to have become a tradition in my group at ARM that on one's birthday, as well as buying doughnuts for the group, one also poses a puzzle of some sort whose solution is one's age. This seems like a fun enough tradition to propagate, so I'm going to do it here too.

At work last week I told hsenag that there was a really obvious puzzle for this age which I'd have to avoid using, and he correctly guessed my age just from that. If you can do the same, you can give yourself a particularly smug pat on the back.

For everyone else, here's a nonogram puzzle I prepared in advance. You can print it out and solve it on paper if you like: http://www.tartarus.org/~simon/20050503-birthday-puzzle/nonogram.pdf or http://www.tartarus.org/~simon/20050503-birthday-puzzle/nonogram.png.

Alternatively, anyone who has the ‘Pattern’ program from my puzzle collection should be able to just type in 15x10:1.4/2.5/1.1.1/1.2.1/1.1.1/5.1/3.1/3/7/4.2/2.1.1/1.1.1/1.1.2/9/3.3/5.4/2.2.2.2/2.2.2/2.2.2/3.6/3.2.2/2.2.2/2.2.2/2.2.2/7.4 and solve the puzzle in comfort on-screen.
