Peter van Munster sent me this picture yesterday. As you see it’s another impossible object. Colud you construct this thing in real life?

It’s a variant on the impossible triangle, this time it’s a rectangle.” If you also have some interesting illusional pictures, feel free to submit them to my email adress (in the sidebar), and if they are good,we’ll publish them online!
