Labouring under the pall of January? Mood insufficiently boosted by your book? My advice: set aside five minutes and watch these two slivers of stop-motion genius, created by selfstyled "crazedadman". The first, uploaded in July last year, shows what happened when Mr Adman and his wife "decided to organise the bookcase". As the hands of clock stutter towards midnight, the books dart and zoom across the shelves, climbing up and edging out and even, at one point, forming a breaking sea on which a banana bobs like a lifeboat. It's beautiful – but it's as nothing to what happens when they decide to take on a bookshop.

I came to these films with the advantage of not having an earthly clue how stop-motion actually works (how do they get the book covers to open without being in the shot themselves? how?) so as far as I'm concerned the whole thing is engineered by honest-to-goodness witchcraft. But either way, there's something properly awe-inspiring about watching the books dance across the shop, the shelves turning into streams of flickering colour. Lovely stuff.
