Need to implement a method of synchronising screen updates, as well as visual halts with everything else (HARP ONIX)
Proposed solution is to use a flickering quad somewhere in the corner of the screen with a photodiode recording. The parameters of this flicker (e.g. color) should be changed during halt periods so we can recover both the screen update as well as the timing of each halt.
