If you may combine RUEDA TORNO with RUEDA LLANTA and RUEDA MIXTA you get RUEDA CALEIDESCOPIO. This structure requires an even number of couples, preferably not less than 8 couples, and you need fairly experienced Rueda dancers.
Rueda caleidescopio will result in a few more new positions, similar to the radios (spokes) positions in Rueda torno: llanta radios (llanta spokes) and radios largas (long spokes).
This universe of variations can easily be associated with a caleidescope, hence the name. It requires an even number of couples, preferably not less than 8 couples, and you need fairly experienced Rueda dancers.
This is not a very fixed structure, it is more of a frame for exploring new variations of combining several of the previously developed Ryeda structures. It is a bit hard to visualise just from text and a diagram, so here is a couple of videos from Sassan Ito, leading his Berlin Rueda group in Rueda caleidescopio:
Here is also a video from a Rueda torno workshop by Jaroslav Hluch at SalsaNor’s Rueda Congress 2016 in Trondheim, where Jaro is also expanding the Rueda torno idea using elements from Rueda caleidescopia:
Here is an illustration of the transitions between Rueda de casino, Rueda por fuera, Rueda llanta and Rueda mixta used in Jaro’s video:
