Secret Santa suggestions please

[ISawMamaPizzaKissingSantaClaus]

Need to pick your brains. Trying to find two secret santa presents. I prefer getting 'proper' things rather than jokey, useless stuff. These are the recipients:

1st: male, maths teacher, early 30s, stylish, alcohol and food not allowed, limit £5 - thinking something geeky, mathsy, any ideas?

2nd: female, English teacher, late 20s, girly, loves dragons, limit £10 - diary with dragons maybe?

Hope someone can help me find the perfect presents

English teacher - a Penguin books mug, or Waterstones have some lovely new ones with 'Frankenstein' or 'Lord Of The Flies' amongst others - and a bookmark, especially if you can find one with a dragon on. Not a diary - people who use diaries tend to be fussy about the type they have and people who don't use them aren't suddenly likely to start even if it has dragons on imho.

Maths teacher - no idea, sorry.

Female-a dragons egg from Lush. It's a bath bomb with sparkles and confetti in

Man-don't know. Sorry

Thanks, fab ideas. I will go with a dragon bookmark (loads on ebay) and the dragon bath bomb. Perfect, as she is girly and loves dragons, so one gift for each of her passions / personality.

For the man, how does a day to day block calendar with sudoku or riddles sound? You know, those where you rip off one page a day and have a little something to read / do. Stupid £5 limit, can't think of anything nice and geeky.

Science Museum toy for the geeky bloke, here's one for £4.99 (half price) :

That Science Museum geeky toy is great! DS got it last year and I've bought it for a friend's teen this year.
