Jastrow Illusion

I found this illusion very interesting due to its simplicity, but also due to the potential implications in reality. Particularly, how it could come up in everyday situations involving food. I thought the music video was very appropriate in the context of your project. However, I've no idea how you'd use this illusion in another work.

Nice project! I thought you did a really good job explaining the hypothesized explanation for this illusion, especially considering people are not totally sure how or why it really works. I also really liked how you used such real world examples like the slices of cake and fruit. You did a good job showing that this phenomena is relevant in real life, not just in art.

I enjoyed the anime clip as well as your two amusing examples. What effect do you think this illusion could have in works of art, besides providing a somewhat humorous or entertaining element? What kind of intentional effects could it be used to create?

I thought your examples of Jastrow Illusion were great especially the one from Detective Conan which had a good explanation for the effect that was very easy to understand. What was really interesting to me that chose you examples that had varying "severity" (I guess that would be the word) of the illusion, meaning that some of your examples seemed to be much different from each other. For instance, to me, the cats appear to be very similar in size whereas the railroad tracks seem to wildly differ in size. I don't know if that's universal but if so maybe you would want to talk about how placement of the objects increases the sense of the illusion. Also if you were to make a piece using this illusion how would you do it?

Actually, I often find that the severity of the illusion depends very much on the placement of the two objects. If you remember from the video, they show the illusion where the two semi-vertical edges of the objects are lines up, which increases the severity of the illusion, while if the two objects are just stacked on top of each other, the illusion is much harder to see and usually doesn't actually trick the eye as much. As for using this illusion, well, I've had difficulty thinking about it, but I think a good way would be in a piece that requires either the audience to move around it, so probably a 3D piece, or for the piece to move, like in an animation. Actually, going back to the real world examples, I think perhaps using the rail tracks might be appropriate -two tracks that look to be different sizes but actually are the same length, which can then be disassembled and reassembled. I feel that would definitely make for and interesting animation at least. Another thing, while not digital art, I feel this could definitely be used in sculpture, where looking at the piece from one angle may make certain parts of the piece seem larger, which I think would be fun to trick the viewer
