+make a realistic breakdown between technicalities (ie audio, mapping) and content

+a better way to plan scanning area not pixel based? guess warp scale is ok for now
+subtlety not really the thing?
+drawing dots would be good.
+warping dots in interesting ways

+
+1- make dots work (+mirror?) - why- atm does it not
+2- an FFT thing with bars, similar, what's the ideal interface

+- audio input
+- mapping
+- fix length overlap
