I may have a go at this :
http://bmagblog.wordpress.com/2013/06/04/staffordshire-hoard-challenge-for-museum-cake-day/ The idea is basically that you make a cake in the form of / inspired by the
Staffordshire Hoard - that is the huge Anglo Saxon hoard from 7-8th century Mercia that turned up a few years ago - and then tweet or Facebook it to them by June 19th.
I reckon I could do quite a good Dave the Silver Gilded Pommel Cap, in chocolate fudge, although it's rather tempting to try to recreate an entire object that the odds and ends found in the hoard would originally have belonged to. In cake. I don't think I could work in biscuit. Too crumbly. :-D
