Hotel Toilet Fun (no, it's not what you think, I'm afraid)

I'm writing this in a very funky Leicester hotel room because I'm at the Local Government Association Climate Change Conference.

The bathroom has a dim light that comes on when you go in and automatically switches off when no motion (ahem) is detected, normally when you've left. Brilliant in eco-terms, but if you nip to use the loo, it switches off unless you keep moving.

Toilet dancing - it'll be the next big thing - you heard it here first.
