Shepard tables[edit]

The two "tabletops" in the Shepard tables illusion are identical parallelograms.

Comment: I literally had to measure both figures to convince myself that they have the same dimensions.

Comment. This is fascinating, but the article does not appear to be long enough at present -- 1500 characters of prose are required. Can you expand it? Espresso Addict (talk) 06:45, 10 February 2019 (UTC)

Thanks for letting me know @Espresso Addict:. I added more information -- according to Shubinator's DYK check it is now 1948 characters long. It was fun creating this and I am glad you enjoyed reading it. HouseOfChange (talk) 19:49, 10 February 2019 (UTC)

New non-stub article, length now fine, neutral, appropriately sourced. Earwig found no copyright violation, but I have not been able to check all sources. Suggested image appears in article, is appropriately licensed; works well at small size. QPQ done. Both hooks are concise & interesting; the fact is stated in the article, cited to reliable source. I prefer Alt 1 (but see below) if the image can be used, otherwise the main hook, which stands alone (without the image) better.

The following points need attention:

Hooks need to include "pictured"/"example pictured" in the appropriate place
"identical in shape and size" in hook Alt 1 is the same as OUP source (ref 1) and needs rewording
It's not clear why the second image in article is under a cc license. This needs explaining or removing
The article feels a bit quotation heavy; it might be better to reword the Dictionary of Psychology quotation at the start of paragraph 2
Is the quotation sourced to 2 actually from offline source 2, or was it actually sourced from 1? Unless you've personally verified it in a copy of 2, it should reference the source you actually used. Espresso Addict (talk) 23:03, 10 February 2019 (UTC)

(restarting indents) @Espresso Addict: Thanks for very helpful advice. I repaired the hooks and article as you suggest. I will look in the library Monday for Mind Sights to verify or change those quotations. (I ordered my own copy last week, but I don't have it yet. I was inspired to write about Shepard by seeing somebody else's copy of the book.) HouseOfChange (talk) 03:26, 11 February 2019 (UTC)

Ping me when you'd like me to re-review (I don't use a watchlist). Espresso Addict (talk) 05:38, 11 February 2019 (UTC)

After verifying quotes in my friend's copy of Mind Sights, I expanded the quote inside its citation. The article is ready for re-review now, if you have time, @Espresso Addict:. Thanks for your help! HouseOfChange (talk) 01:43, 12 February 2019 (UTC)

Thanks! Looks good now, HouseOfChange. I'd personally still rewrite the Dictionary of Psychology quotation in my own words, but that certainly isn't a requirement for DYK. I hope it can run with the image. Espresso Addict (talk) 04:21, 13 February 2019 (UTC)
