I've been designing a new icon for a new non-document object we're planning.
I had wondered if there was specifications for ideal icon resolution and size. Of course in my research I found this:

Love some of the new icons - so my org's October release is going to see some of our icons 'refreshed'!
Thought I would share in case this is of interest to others :)
