Visual perspective

Maybe some mention should be made that some play occurs in the image with respect to contrasts in visual perspective. I.e., the foreground is drawn in axonometric projection, while the background is drawn in perspective projection. This provides some marked contrast to further confuse the viewer.

Cool animation

Here is a cool animation showing what the structure might look like in real life (here is the text description for the movie). Should it be linked to from the article? SharkD (talk) 07:10, 22 December 2007 (UTC)[reply]

This is what is known as a line of sight illusion. In the animation, the split has been made at the top of the waterfall, but it could have been made anywhere along the water course, or there could be more than one split, provided all the bits fit together nicely when viewed from the intended angle.

Water running upward?

I thought the reason it was an illusion was because the water was meant to be going downhill all the way. The first paragraph says differently though.Jezzamon (talk) 00:12, 30 August 2008 (UTC)[reply]

I agree that it's unclear - so initially made it downhill, then re-edited to clarify. It's going uphill, but if you look at just the path of the water moving up, it appears to go downhill. Nineran (talk) 15:33, 29 October 2012 (UTC)[reply]

What seems to violate conservation?

The article claims the drawing seems to but surely it is what is depicted and not the depiction which does the apparent violating? -- 15:33, 23 July 2011‎ 131.251.142.154
