Hey Brian, Based on your thoughts on the backgrounds I redid the video for Head so that the representation of the atom becomes a solid blue background instead of ring when it is made into a one item list.
Hopefully this consistency will help the understanding as we move forward. The new video is posted here. https://youtu.be/FV9G5zeRnPg Cheers, bob > On Jun 2, 2019, at 8:45 AM, 'robert therriault' via Programming > <[email protected]> wrote: > > Thanks Brian, that is great feedback. > > It was the true intent and you are right that I should mention it. > > Also, the reason that the atom example has only a blue border is that the > shape of an atom is empty, whereas the solid blue indicate the shape of the > items.
