The Spot

the yellow only joins up from one place. find it.

turn a manga-style street crossing until yellow paint spread over boards at different distances joins into one shape, against a 45 second clock

A picture is flat: it keeps where things are across and up, and throws away how far away they are. So pieces of paint on boards at different distances can join into one clean shape, but only from one place, which is how Felice Varini's painted murals work. Turn the street until the yellow closes up.

Concepts: perspective, projection, illusion.
