Such a great idea!
At @elife.bsky.social you can now include explainer videos with every figure. Like going to a seminar while you engage with the paper. First example here elifesciences.org/articles/106...
Click the arrows next to each figure to get a video of @mathiassablemeyer.bsky.social explaining it for you!

When future historians look back to describe what’s happening today, they will need independent local media reports to make an accurate reconstruction. Corp media will not be a reliable source. Support local independent journalism, for today’s sake but also for future generations.
