I must be thick but I've spend hours on this on several days.

I've imagined I've seen numbers in bricks (especially the number 4) and so on only to be told I'm a fool.

Perhaps you could give a clue to idiots like me who can't figure it out. Or at least give us a second best download for trying even if we are too stupid...

It is Christmas soon - perhaps you could tell me what corner to look in as I'm to dumb to find it myself.
