A Crabby Little Spider?

What's this then, any ideas?? No, not the cherry tree...the little bug above that ripening cherry. I thought I'd seen all the bugs in the garden but this very very pale green spider beats me!. It holds it's two pairs of front legs up like a crab. I've checked all my bug books but maybe Google will know!
I'm home now so should be back to normal crafting very soon! Apologies to everyone who hates spiders!
