<div class="jetpack-video-wrapper"><iframe title="the Infinity Puzzle" src="https://player.vimeo.com/video/192681460?dnt=1&amp;app_id=122963" width="640" height="360" frameborder="0" allow="autoplay; fullscreen; picture-in-picture; clipboard-write"></iframe></div>
<p>Inspired by topological spaces that continuously tile, <a href="https://n-e-r-v-o-u-s.com/blog/?p=7613" target="_blank" rel="noopener">the infinity puzzle</a> has no fixed shape, no starting point, and no edges, and can be assembled in thousands of different ways. It&#8217;s a pretty challenging wood puzzle that tiles in the plane, meaning that any piece on the bottom can be moved to the top and a piece on the right can be moved to the left. Topologically, it is equivalent to a torus, which can be described by its fundamental polygon showing how edges of a square map to each other to make a closed shape.</p>

<p>The single pack costs $40, comes with 51 pieces in smallest size at 6&#215;6 inches. Multiple copies of the puzzle can be combined in different colors to create abstract patterns and shapes.</p>The post <a href="https://www.kjctech.net/the-infinity-puzzle/">The Infinity Puzzle</a> first appeared on <a href="https://www.kjctech.net">KC's Blog</a>.]]></content:encoded>
