Experiências visuais
Imagens que enganam Experimentos curtos com cor, movimento e forma. Cada um leva menos de um minuto, pergunta o que você viu e depois explica o que seus olhos estavam fazendo. É um jogo sobre percepção — não um teste da sua visão nem de qualquer outra coisa.

Geometria The Hidden Line A line runs behind a band and comes out the other side. Three lines come out; only one is it. Geometria Parallel Lines Six long slanting lines, crossed with short strokes, and a question about whether they run side by side. Geometria Bowed Lines Two red lines across a burst of rays. Are they straight? Geometria Ring Around Two dark discs, one in a tight ring and one in a wide one. Geometria Two Arches Two curved shapes, one above the other. One of them is bigger — or is it? Geometria The Tall T An upside-down T. Which of its two lines is longer? Geometria The Parallelogram Two red diagonals in two parallelograms, a big one and a small one. Geometria Filled Space Two stretches between three marks: one filled with ticks, one left empty. Geometria The Company It Keeps Two orange circles, two crowds around them, and one question about size. Geometria Equal Lines Two lines, a few fins, and a question that is easier to answer than it looks.
