Link to Wide->Telephto FOV Image from a while back?

Someone posted a link a few weeks back (or an image itself, I can't recall) showing the various crop marks representing different fields of view for different focal lengths.

I think the widest was 10-12mm and the centre of the image was a telephoto crop that would represent 200mm or so. Does anyone recall what that link was or have a copy of the image? Does anyone know what I'm talking about at all? TIA

I distinctly remember the picture, but cannot locate it.

I think the photo was posted in 2007, perhaps around summer. I believe that the discussion was about how significantly 1mm of focal length affects FOV in wide angle compared to telephoto. A poster posted a photo (of his creation?) which had maybe 10mm FOV, and had a series of concentric red rectangles drawn on, representing FOVs at different focal lengths.

I am pretty sure the original post was done by Richard Day, but I can't find it.
