..well, not really 'art', but.. Did-purposefully work that effect in w/ the DP on this vid http://www.laserium.com/video/Angels...cinations.html to 'sync the interference' w/ the synth-beds / drum-segs in the track.. mostly, in the 'ribbon-scans' / logo-scenes, later in the vid (..after ~3:05-ish, iirc.) ..was kind of an interesting 'end-result', where the scan-flicker 'appeared synced' w/ the beats, as-per intention..
..sure, not the 'greatest example of lasers-in-video', by a long-shot, but, hey.. at least I got a machita in there..
