I' ve just been to FAD festival in Belo Horizonte, Brasil. I was pretty much impressed with the quality of all the gallery works so I'll post here in the next few days just a few lines about each project in the gallery.
ADA is an interactive, analog, installation where the visitor interacts with a large plastic bubble filled with air and helium inside a white room. The bubble is spiked with charcoal that leaves marks on the ceiling, floor and walls. Although the bubble is apparently easy to control, when you try it, you realise that you cannot really control it. You can give an initial direction and speed, but it rapidly regains its apparently autonomous movement, maybe due to the weight differences between the helium and the air inside it, which generate a changing center of mass inside it.
