Wilhelm Wundt, a German psychologist described this illusion in the 19th century. In this illusion, both red lines are parallel to each other but due to the other lines, it may seem that these two red lines are not parallel.

Are all the four lines of same size? Many of you might think the horizontal line which makes the top of T is shorted but actually its not. These all are of exactly same length.

Where is that dot? Is it on front or in back?

Looks like the civil engineers have left the work in between. This is the Storseisundet Bridge in Norwaywhich connects mainland Romsdal peninsula to the island of Averoya. On seeing this picture it looks like the vehicles will have a steep fall but actually its just the way this picture is being taken. The bridge is complete and operational.

The complete picture shows this civil engineering marvel.
