I thought it would be fun to invite people to try out this game you can play with your standard digital camera (as long as you can film on it too).

All you do is ask someone if you can take a photo of them. Then, if they say yes, actually start filming them instead. I did one, which you can see here.

I asked people to send in their attempts too. Here's a couple:

This one was sent in Paul - its of his Mum and Nan. (always easier to fool the oldies)

 This one is from "Rich-Dizzle"!

If you want to do one, email me the link - greg.james@bbc.co.uk
