The same sessions as the DC page, played as a film. Each glowing packet is a real message from the protocol, coloured by the layer it travels on, flying from the side that sends it; repeating loops stream steadily, and the cable glows with the voltage on it and floods amber when current flows. Time is stretched where messages come thick and fast and squeezed through the twenty minutes of charging. Pick a protocol and press play.

Every packet is a message from the DC session model, in order, from the side that sends it. The clock is stretched so each one can be seen, so this is not real time: SLAC's sounds really are 40 ms apart, and the charging in the middle really lasts about twenty minutes. The page with the sequence diagram has every message's fields and sources.
