I watch/read everything I can about the JWST! The fact that it will be unfolded once it is in position in orbit is just one of its many amazing features. Here are two of my favourite videos about it:

I was going just to post one, but they are both equally good...
This image not only captures the galaxy and its backdrop in stunning detail, but also something more dramatic — intense blue streaks streaming outwards from the galaxy, seen shining brightly in ultraviolet light.
These streaks are actually hot young stars, encased in wispy streams of gas that are being torn away from the galaxy by its surroundings as it moves through space. This violent galactic disrobing is due to a process known as ram pressure stripping — a drag force felt by an object moving through a fluid [1]. The fluid in question here is superheated gas, which lurks at the centres of galaxy clusters.
I thought I'd posted these images earlier, or that someone had, but I can't find them on the board. Apologies if I'm duplicating!
There is also a useful ESO video (Hubblecast 72: Clues to a Violent Crime) which explains "ram pressure stripping" in a way that helped ME to "get" it. https://www.youtube.com/watch?v=oL2nMtQtdDY
Seeing a news blog on the Sky and Telescope website today reminded me, as I thought I'd just be adding the Sky and Telescope link to an existing thread.
The webpage describes this as an image of NGC 3842, this is the central elliptical galaxy of this galaxy cluster. There are many more interesting galaxies that are outside this frame.
