Here is a video with gold pigment and alcohol and some acrylic fixative. The idea was that the alchohol would evaporate overnight leaving the fixed gold pigment in the place the wave form left it (another attempt at producing a physical drawing) THe end result did not turn out that well however there was slight evidence of the patterns made in certain parts.. if you look at the first seconds of this video though, the wave form seems pretty present so i thought it was pretty promising but it the actual product was not as hoped... maybe it just has to be the right day and needs to be tried again... also, when thinking about how to get rid of the tray sides, i was scared of cutting away at it for fear that the flakes would not be fixed enough and everything would fly off when snipped! Either or, its worth more explorations in the future.
