Great detail and contrasting colours Jim, looks like a running crab spider of some variety.
he was quite nippy, and reminded me of a cartoon character running round and round the world (apple in this case) every time i got too close, he'd run around then settle back where he started, now outside somewhere :)
thanks for the hint, your right its a Philodromus albidus, heres a naturespot link for more details, and another pic from the top down when it was sitting atop the apple stalk
