Who Dunnit - Observation Test

I hate these things. I can drive down a street for the umteen-hundredth time and not notice that number x has been knocked down and rebuilt! :confused:
I notice changes when i drive, like if someone comes out infront of me, i'm aware..

But i'm not looking for a change in a murder scene :p

I do enjoy these things though, it's so obvious, but not!
Wow I got a total of 1!! (without realising that changes were occuring at all - which is a bit of a spoiler really).
