I'm more familiar with that one than the one in swindon. It looks extremely terrifying from above, but what it actually looks like from the ground is a bit of a weird run of roundabouts one after another. If you take them one at a time rather than consider the intersection as a whole, it works fairly simply. It's actually shockingly intuitive.
Compared to the nearby roundabout onto the M40, which is of a much simpler design, but is covered in traffic lights, the Wycombe magic roundabout is actually much better at moving traffic around.

There's also one in High Wycombe. https://www.google.com/maps/place/High+Wycombe,+UK/@51.62697...

Handy Cross is the worst roundabout in the country, I hate it so much!
