Was expecting it to be like those weird 3D pictures where you stare at it for ages and a picture morphs out of the background...jumped a frickin mile when I spotted the guy!
Didn't manage to get it at all from the small pic...once I twigged that you could make it bigger it took about 6 seconds. Although the fact that it took me so long to work out that the pic could be made bigger probably says more about my intelligence (or lack thereof) than the actual test!
