Can radio make good "TV"? For the past couple of weeks on Today, we've been conducting an experiment: filming the goings-on in our studio so that it's now possible not only to listen to the programme, but also to watch some of it.
Many radio interviews, of course, aren't done face-to-face, but "down the line" with the interviewee in a different studio. It's fair to say that when presenter and guest are together, it usually makes their encounter a much better listen.
As my colleague Brett Spencer has written regarding similar experiments at 5 Live, the results are making for interesting viewing. Our experiences can be seen on the Today site, among them Sarah Montague's grilling of BBC Trust Chairman Sir Michael Lyons, Labour MP Stephen Pound describing the expenses scandal as "like a slasher-movie", and Michael Horowitz insisting that there is still honour among poets.
Experimenting with what is grandly called "visualisation" is hardly new. For us, the idea was to see whether the cameras could capture something of the intensity of interviews, as well as to give an insight into the working of the programme.
It also gives us the tools to bring out the lighter side of what we do - the nervous swinging legs of the young Scouts accompanying their new chief Bear Grylls for instance.
We've also filmed the presenters' daily review of the programme in the studio, so that you can see exactly what they thought of what we'd just broadcast.
And while we hope that the added visual dimension makes the programme more accessible and appealing online, Today TV isn't here yet. And of course the bigger question is: does it mean that the magic of radio is lost? We'll see. And so can you.
