Help with animation (Facer Creator)

Hi everyone, can somebody tell me which expression to use to show image in 3-second loop (2 seconds on and then 1 second off )

General purpose formulae:

as request …

period: 3 seconds [3x 1000ms]
duty cycle: on 66.6%; off 33.3%


more exotic …

period: 1 second(s) [5x 200ms]
duty cycle: on 60%; off 40%


Many thanks Andrew ! :slightly_smiling_face:
