Those few seconds of spectral figure took hours and hours and hours to create, so I'm glad that you enjoyed that! :)
It was interesting to see people reacting to the work without context, other than the word 'lingering'; however the appaling thing about video art as a media is that on average, people spend about about 14 seconds looking at it. You don't know which fourteen seconds they're going to look at; either. Makes it difficult.
Maybe there should be a 14 second version of this on loop... :D
14 seconds is still 6 seconds more than the average attention span these days... I generally try to watch video installations all the way through 1 loop, though admittedly if they don't capture my interest in a few minutes, I get restless. Yours struck just the right balance I think.
