Microscopic footage of a needle moving across the grooves of a record

Maybe you could use a strobe effect: Have an audio sample that loops every 1/100th of a second, and then put a "fan" spinning at the same rate in front of the electron source, which blocks the electrons except for 1/60th or less of the 1/100th of a second. As you vary the phase of the fan, you capture the needle at different positions in the loop.

That would have been possible if he were able to observe the vinyl in action and had a circular track of audio on the record, instead of working with a square slice.
