      <title>Triangle impossible</title>

      <description>The famous impossible Penrose triangle made possible, size 6.53cm x 2.11cm x 5.66cm&lt;br&gt;&lt;/br&gt;&lt;img alt=&quot;Triangle_impossible_dwf_showroom_image&quot; src=&quot;http://static1.ponoko.com/design_images/images/44524/cc638431-a776-d40b-e717-f4e42502fbc5/triangle_impossible_dwf_showroom_image.png?1307453828&quot; /&gt;</description>

      <title>Impossible Penrose triangle</title>
      <link>http://assets.ponoko.com/showroom/trompe/6356</link>
      <description>The &quot;impossible&quot; tribar, also known as the Penrose triangle. This fantastic optical illusion has now been made possible through 3D printing. We have further enhanced the illusion by breaking it into cubes and added the dots of a die.

Watch the video:
    http://youtu.be/1HAqORTBSV0

A truly three-dimensional object, only made possible with a very special design trick. Please be aware that unlike other attempts to create a Penrose triangle, this model does not have any hidden openings nor hidden twists.

The model is 7.5&quot; (19 cm) high and will come with a matching stand.&lt;br&gt;&lt;/br&gt;&lt;img alt=&quot;I3_showroom_image&quot; src=&quot;http://static2.ponoko.com/design_images/images/32108/ca1d0a0f-948f-636d-c10b-d799cd5728ff/i3_showroom_image.jpg?1314893367&quot; /&gt;</description>

      <title>Penrose tile coasters, clear acrylic, set of 8</title>
      <link>http://www.ponoko.com/showroom/PhaseSpaceDesign/9981</link>
      <description>Set of 8 (2 sets of 4 patterns) thick, transparent acrylic coasters, laser cut and engraved into the shapes of Penrose tiles. (Penrose tiles form an infinitely non-repeating pattern out of 2 basic shapes.) Sharp, clean lines and precision fitting. Pieces are irreglar, but roughly between 4.4&#8211;6.6&quot; diameter. Due to the nature of Penrose tiling, there's no one way to fit them together. Photos show 0.354&quot; thick acrylic. Glass of ros&#233; not included ;)

Please note, the pattern isn't designed to tile into an expandable, solid surface of Penrose tiles. Rather, the tiles are configured to lock together into interesting compositions that emphasize a dynamic, asymmetrical aesthetic.&lt;br&gt;&lt;/br&gt;&lt;img alt=&quot;Penrose-coasters-h-1_showroom_image&quot; src=&quot;http://static3.ponoko.com/design_images/images/71263/0f6d0090-8f04-1883-5c0b-b2597df85bb2/penrose-coasters-h-1_showroom_image.jpg?1368071798&quot; /&gt;</description>

      <link>http://www.ponoko.com/showroom/PhaseSpaceDesign/9983</link>
      <description>A thick, transparent acrylic coaster, laser cut and engraved into the shapes of Penrose tiles. (Penrose tiles form an infinitely non-repeating pattern out of 2 basic shapes.) This is one of a series of 4 distinct patterns (see my showroom) that can be joined together in a variety of ways. Sharp, clean lines and precision fitting. Photo shows 0.354&quot; thick acrylic. Roughly 6.8x5.4&quot;.
