Tam, concentrate on the dark spacing underneath the big stone on the top right hand side. The part where it looks like something peeping out of between the stones.
On the same topic, can anyone remember those puzzles which were extremely popular in the 90s. I can't remember the name, might have been something like Magic Eye. Basically it was a drawing of seemingly meaningless coloured lines. When you stared at it long enough it turned into a 3D picture. Never seen any for ages.
i have studied it long and hard, but I probably wont see it even if i knew what to look for. I am registered blind but have a little sight.I a;so have glaucoma, tunnel vision and I am colour blind..
Feel for you Georgiesmum,very frustrating, I am registered partially sighted, with acute open angle glaucoma - however I have sufficient vision to get me through most things with a bit of adjustment here and there.
