Lines 7 is part of the Lines series. In this version, the concept of optical illusions is demonstrated in this simulation. Press play and watch. Before your eyes you should see rings of some sort, these rings are not actually there. There are only lines, between them is empty white space. Your brain has been fooled, you are imagining things that aren't actually there! ;)
