If anyone still clings to outdated assumptions about classical music and the announcers on BBC Radio 3, then a quick trip to their temporary pop-up studio at the Festival Hall will soon put them to rights. The permanent studios may be better appointed, but in their little box, apart from a striking high-tech clock display, the electronics are confined to anonymous black boxes, and the desk is like anyone else's: breakfast cereals, coffee cups and in this case a screensaver of a very fluffy cat.

As ever, the Hall had plenty of other things going on, in particular a chance to try the virtual orchestra: a virtual reality headset puts you in the front row of the Philharmonia Orchestra's violins, right under the conductor - unless you choose to look around the 360° 3-D display. Not, perhaps, quite high-definition enough to be totally immersive, but still impressive. Perhaps one day we could experience whole concerts like this (but they'll have to make wearing the headsets a less sweaty experience).

Just to complete the cultural delights of the day, the new occupant of Trafalgar Square's Fourth Plinth has just been unveiled - a gigantic, elongated thumbs up. I'm not sure if it's to be taken superficially as intended to make everyone feel good about life, art and the universe (for the artist it is - you can buy a replica from a tent on Trafalgar Square for a mere £25 a pop) - or a satirical comment on superficial optimists. Pick your angle right and you might think the elongated thumb looks suspiciously like a middle finger.
