Original – A peripheral drift illusion
Reason
Despite being the majority coordinator for POTD, I don't often nominate FPCs and I'm not even really an image expert... but this one looks quite impressive to me - the illusion is very profound when the picture is expanded, it seems like it has solid EV as a good illustration of both Peripheral drift illusion and Illusory motion. As an expandable svg it is technically sound too, so I think most of WP:Featured picture criteria would be met. Interested what you guys think of this.
Comment – Leaning to support, but I have a question. The original by Paul Nasca [1] displays as a 27 x 20 cell matrix (with a corresponding vector field here [2]). The nom SVX displays as a 20 x 15 cell matrix. Does that affect anything regarding the perception or illusion? I can't tell with my eyes. Second, personally I like to see Paul Nasca's name mentioned in some way in the file page of the SVG. Bammesk (talk) 14:44, 9 December 2023 (UTC)[reply]
Paul Nasca's name added as requested.
I'm no expert in this field and Google couldn't find analysis on its effect. My original-research opinion is that one needs a minimum number to work (2×2 likely won't) but not so many that detail is lost due to limited display or eye resolution e.g. in a thumbnail. The amount of field of view it spans seems far more important.
