I love smarties.

I love smarties (and I am not referring to the candy) ....just my son John:) He created this graph (that is about as technical as I get). I smiled as he lovingly and with a tad bit of long-suffering, tempered with futility, explained to me what it was. The futility being I cannot remember....but I do have a picture of it:)

John is a good guy and a great student. Love him!
