Talk:Grid illusion

Gobbledegook
ugh, this is what we looked at in Adv.Geometry to today for about ten minutes. andrew  23:06, 7 September 2006 (UTC) this illusion makes you see black dots white

when i was young my mother had a dress that had this effect. i tried to tell her what i saw but she didn't understand.

I think this is a great visual illustration of the Schrödinger's cat paradox where the act of observation causes the observed thing to "settle" on a solution - although in this case of course it always settles on "not a black dot"

White grid
Does anyone else have the white version of the grid in this article "not work" for them? The others do. That's odd.... *Vendetta* (whois talk edits) 04:57, 20 July 2007 (UTC)

Anyone want to do a PhD on the below ???? (Pity it would be WP:OR)



This edit 07:15, 18 October 2007 by CommonsDelinker changed one of 3 images initially added here which was a not-quite identical image for just a duplicate, making captions and this section meaningless, I've deleted out the wrongly captioned duplicate. (3rd original image now a red-link so can not be reinserted to this discussion thread) David Ruben Talk 02:18, 1 March 2008 (UTC)

Images
Can somebody replace the Hermann grid image? It has been replaced with a scintillating grid and the original file deleted. Famousdog 13:03, 18 October 2007 (UTC)

When correcting additions, do it correctly
removing entire sections due to rogue elements or additions is explicitly advised against. If someone's gallery is bad, then you strike IT, not 5 other sections unrelated to their mess. —Preceding unsigned comment added by 68.9.59.193 (talk • contribs) 19:38, 29 February 2008


 * But if the other material is speculation and original research (see WP:NOR) then not only was it not WP:Cited, but you even confimed " ", so the material is not WP:Verified and so not appropriate to include. Removal therefore within policy and guidelines, I've added a welcome note to your talk page then sets out main policies and guidelines.David Ruben Talk 02:10, 1 March 2008 (UTC)

white grid errors, intensity
proportionately, the white grid's midtone is too light, average luminosity should be either 1/3 or 2/3 total optical luminosity... aka the grid should be dark on white, but slightly brighter than mid-range on black due to wider human sensitivity to light... also sunlight is much brighter than your monitor, lcd panels typically do not work with higher resolution illusions -- I'll tell the researchers about the inquiry. —Preceding unsigned comment added by 68.9.59.193 (talk) 18:42, 29 February 2008 (UTC)
