I think the current Wikipedia entry for Oscar Reutersvard may be seriously misleading: https://en.wikipedia.org/wiki/Oscar_Reutersv%C3%A4rd because it credits him with inventing the Penrose triangle rather than the triangle made of nine cubes, which is far more interesting than the Penrose triangle.

There are many online web pages providing the Reutersvard triangle, for example this one: http://psylux.psych.tu-dresden.de/i1/kaw/diverses%20Material/www.illusionworks.com/html/art_of_reutersvard.html

I shall not directly edit the current page, because I am not an authority on Reutersvard, and it may be that the history I've picked up from reading about him in the distant past is mistaken. I hope someone who knows more (or has time to do the required research) will remedy the situation.
