Daaad, where's that unique piece of lego?

I was more than happy when youngest asked if I could get the lego out for him. 5 minutes later he was asking if I could help him find a unique piece of it. From among this pile. We have lego going back 40 years from my youth, my nephews and three children and this mound is what is left after we gave away at least half of it. I'm glad to say I found the bit fairly quickly, and an inordinate number of disembodied hands...
