firstly there are the letters xyz placed on top of each other, then there is the symbol for pi underneath with an arrow pointing at it, then on the right of these is the name alan titchmarsh.
there is a film called pi but this does not seem to answer the whole dingbat.
any ideas please.
Yes, I've just spotted that you said the arrow is pointing just to the Pi rather than the xyz so the xy and z are red herrings and The Constant Gardener is right
