Wow, way cool. It's like I had to adjust my eyes in *just* the right way, and ended up seeing the circles!

I definitely saw the circles right away, and I wonder why that is.

I saw circles first too. Maybe it's because I read the question first so I was looking for circles. Had the question been below the image, then I might have seen the rectangles. I think it's more adjusting of the brain than adjusting of the eyes.

First time viewers of this display invariably do not see the 16 circles segmented from the background.  Rather, they see a series of rectangles that they frequently describe as “door panels”. The illusion pits segmentation cues against what appears to be a very strong prior to interpret the image as a series of 3-D structures “coffers” with closed boundaries.  (A coffer is a decorative sunken panel.) It appears that the prior involves both closure and shape-from shading assumptions. The Coffer Illusion is a variation on Gianni Sarcone’s “Op Art illusion”.</DIV></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/21866F09-2A2D-451A-86D2-2C6E1DBF78AD/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
