media.js — the physical-artifact & human layer.

What a real bubble-chamber frame carried beyond the tracks:
|

• grease-pencil (chinagraph) hand marks — a scanner ringing a
|
||||
"good event", an arrow, the event number, an angle/ticks;
|
||||
• film furniture — sprocket holes, a data box (roll/frame/
|
||||
date), edge stock printing, a frame rebate;
|
||||
• a réseau — the precise grid of small crosses imaged for
|
||||
distortion correction;
|
||||
• a tape splice — long rolls were cut and joined, so a strip
|
||||
is literally taped together, often slightly misregistered.
|
||||
All seeded. Geometry in the logical [-1,1] square.
