Here is a great concept from Vistosi! The elegant satin blown glass shape above is one of four in their WithWhite series.
Each one can be used as a pendant or as a ceiling light -- a good start. But then you discover that they can all be combined to make rise'n'fall lights that don't have a visible counterweight.
The result is 25 options (25 not 24 because the shape above can be used as a ceiling light either way up).
The concept, and how well it works, is easier to grasp in pictures than in words:
The result is a very versatile family of designs. One can use any one of them, obviously, but they really come into their own when you'd like to specify a group of lights in a space but you don't want them all to be the same.
And it gets even better! The rise'n'falls have a lamp in the top part, separately switched. These will provide ambient light, while the pendant part casts direct light onto a surface below.
I know, I know -- there are only 24 options in the pictures above. Here below are diagrams of all 25. Can you work out which is missing? And then tell me?
