[edit] 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)

[edit] 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)

[edit] 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[1] is speculation and original research (see WP:NOR) then not only was it not WP:Cited, but you even confimed "<ref>unkown</ref>", 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)

[edit] 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)
