When I read "tensegrity" I thought of these strange tables/scupltures you can buy:

If you look at the article, you'll see the picture of such sculpture (a rather impressive one, by the way).

A good example are bicycle wheels made with ropes but if you think of it even of steel spokes as a single spoke by itself cannot maintain the structure and it all comes together when the spokes are tensionned. https://berdspokes.com/collections/berd-wheels

Obviously a wheel is the easiest design you can build based on tension given its symmetric nature.

I didn't see that, are you talking about the bird's leg?

The last image is a pair of pictures of Needle Tower and Needle Tower II, which you can search for if the image doesn't load in the article for you.

If that is what "tensegrity" makes you think of, I'm guessing you haven't seen this:
