Spent most of the day trying to come up with something bold and contemporary and youthful for Channel 4's "Coming Up" scheme.
But I did come up with something that might work for Radio 4. So, not entirely wasted.
And I did decide that something I worked on before might usefully be resurrected for Coming Up. In fact, I think it might suit rather well. Deadline's 18 April, so I've got a bit of time to polish it up.
