So I figure now's a good time to let someone else get a word in. Here's a topic: tell me about something you'd really love to see.

I'll start it off: when I was a kid, I read somewhere that if you go up in an aeroplane when the weather conditions are right, you can see a completely circular rainbow. I always wanted to see one of those.

But then, imagine my delight when I noticed you can see them down on the ground! Look at street lamps on a misty night. You get a glowing sphere of light, edged with a rainbow...

So, let's hear: what would you like to see?
