 +PICA
 +  * "Well known that well working gates emit light during switching"
 +  * "Emission is strongest when gate voltage is half of the drain voltage - the midpoint of the logic transition"
 +  * "PICA uses a strobed, intensified detector to gather spatial information and time information"
 +  * Specifically used a ring oscillator as an example of something it can image
