A got the BBC Radiophonic Workshop – A Retrospective from his brother for Christmas, so I can now confirm that the following things sound very much like the arrival of the TARDIS*:

– Sweeping dry pine needles off an Ikea LACK coffee table (only birch finish verified)
– Fumbling around in a terra cotta pot full of rubber bands and binder clips
– Me inhaling during my Christmas cold

That’s right, the lucky boy has the BBC Radiophonic Workshop – A Retrospective and a girl who can make (a very limited range of) Doctor Who sound effects.

*Also a door key on piano wire (and, for the very geeky, other things).
