Yep, the worm loves the stuff and looking at it you are quite lucky as the sapwood can also crack quite a lot while drying as well.
Having said that I had to look twice (having totally missed the first image) to actually realise I was looking at a turning - sorry Les, the angles you picked makes it look like you were showing the timber you'd bought.
However having now seen the first image and realised it is a bowl, you've found an interesting shape in it and finished it and delivered it well.
