I won't talk about NMeth @natmethods.nature.com forever (probably), but I do want to brag a bit about the November focus issue on cell segmentation and tracking, which is many ways is my last hurrah (and final editorial) for the journal.

It would be great if VFX artists refused to work with directors who lie and say they don't use VFX.
It would also be fascinating to see how their movies would look if they actually didn't have any VFX.
