Double Exposure

Played today with one of the apps on my camera phone - a Lomo Camera app, introduced to me by my friend and fellow blipper 'bonnylass' (still have no clue how to put that in yellow but go and look).
One of the options is a double exposure and this is one of those. One straight on, one up towards the ceiling.
The camera takes the two photos and then merges them together - Very clever.
