Impossible Figure: 2012-10-21

I was actually quite intrigued by this design. After sketching it I realized it is not just two interlinked tribars, but you can also trace out a square frame for each axis.


Linework | Fillwork

The cube is enveloped by two intersecting impossible tribars.

    Why the asymmetric placement of red triangles on the center part?

  2. You mean the red squares? (in perspective) :D Haha, it’s a die! I thought the center cube looked very lifeless and hard to distinguish (check out the Linework version) so I added some flavor.

    Heh. I was [i]just[/i] experimenting with Penrose triangles and what I could do to make them more complex (squares, pentagons, etc) and you go and do this awesome frame. Great work.

    Also, I somehow find the division of the bars into two/three colors a bit detracting from the big illusion (even though, it adds a different kind of it). Either way, impressive use of the Penrose illusion.

  4. Yeah, I agree that it gets a bit too dense :P I was running short on time though, and really wanted not have it all in just one color so this is how I divided up the geometry ;) I might revise it at a later date, then to showcase the double-tribar + triple-square feature. Not sure if it is possible yet, hehe, would have to look into it.

    I think it is.
    And I think it will look amazing.

    Kind of like ancient Celtic trefoils, but mind-blowing.

    A few questions…What is you work flow? I mean, do you design/plan your works before putting it together or do you sit down and whatever comes out works? What program do you use?

  7. Hello IVMMX :) I pretty much always sketch on paper, often starting out randomly and then trying to make sense of it. I don’t have the luxury to spend large parts of my time on this so it becomes focused sessions. After that I move to the computer to draw it again. It is explained fairly well on this page:
