Canogar's sculpture made of wire and using light to animate it was a great piece. Unfortunately photos and videos of it did not come out well enough to use. To find out more about the artists and the gallery I suggest heading to maxestrella.com.
Pellón currently lives in France and is 85 years old. She has, in the course of her career, beeo associated with the Surrealists, with COBRA but her work is hard to assign to any single "school." If her work looks familiar it is in a slew of public collections. You can see more of her work at Cernuda Arte (who are always a good place to look for info on Cuban painters).
