I have experimented with different methods to make dancers musicality visibly but still let they have a reasonable amount of privacy.
I have been working with these blurred videos about 6 months now and noticed that my brain is responding in an interesting way. When the usual details are deprived the brain starts to find other things to focus on. Anyhow my brain started to follow the whole bodies, mostly shoulders moving in music. Today some of these videos, especially vals, are sending waves of pleasure along my spine!
There is a clear space traveling around to have some additional stimulation/variation.
