+- [V2 (illustration)](https://www.biorxiv.org/content/biorxiv/early/2021/12/19/2021.07.22.453335/DC2/embed/media-2.mp4?download=true): the GHS-DPP microscopy works
+- [V3 (results)](https://www.biorxiv.org/content/biorxiv/early/2021/12/19/2021.07.22.453335/DC3/embed/media-3.mp4?download=true): Drosophila's ommatidial rhabdomere orientation matches the optic flow during forward translation
+- [V4 (illustration/simulation)](https://www.biorxiv.org/content/biorxiv/early/2021/12/19/2021.07.22.453335/DC4/embed/media-4.mp4?download=true): 
+	a) the number of locally activated photoreceptor microsaccades depends on the angular size of the light stimulus
+	b) the number of ommatidial photoreceptors pooled in the DPP imaging depends on the microscope system's numerical aperture (NA)
+- [V5: (results)](https://www.biorxiv.org/content/biorxiv/early/2021/12/19/2021.07.22.453335/DC5/embed/media-5.mp4?download=true) wild-type and spam microsaccades are
