I posted a tiny clip of some wip animation on twitter (for reference), I figured it's a pretty good way to show some of the progress without having to compromise workflow to create a final-ish render. I'm considering doing more of this in the future, so let me how you feel about it:)
In the case that I do go ahead with this, I'd probably draw a distinction between WIP posts (wireframe/in progress) and Teasers (full renders very close to/final)
