Bicycles in the Wind Origami Tessellation

Image
 So, after having solved 'Hugs in the Rain' by Arseniy K, I had the idea to do a triad of parallelograms around an open back triangle twist and just repeat that. But that felt a little too simple. So I mixed it up a bit with some rhombuses in there as well. It worked out nicely.  The rhombuses  and the parallelograms on the front are both natural folds.  There are small hexagonal twists on the back where the parallelograms converge.  The negative triangle spaces on the front are open back triangle twists on the back.  The negative rhombus spaces on the front are rhombuses with blunted tops and bottoms on the back. I don't know what name that shape has, but you can see it clearly in the photo of the back side.  This model was not difficult to fold. Thin paper worked quite well.  See below for a crease pattern sketch. 

Solving Shy Triangles by Andriy Hechuev

This is based on a design by Andriy Hechuev called 'Shy Triangles'. I found it on Instgram.  The central part of the model is their shy triangles concept.  It stumped me for a little bit. I didn't realize at first that it was all triangle twists. A post by Monika Hankova  revealed that info.  The original design only folded the central area. When I did a tester it didn't entirely fit on a 16 pleat grid. So rather than mess with folding a hexagon into thirds to get 24 pleats, I just went with a 32 pleat grid.  Personally, whenever I try to do thirds on a hexagon it seldom comes out right. I know the steps. I just find them hard to execute accurately.  So, with 32 pleats, I added some additional triangle twists to garnish the edges.  The view of the back side is pretty neat too.  My crease pattern sketch for the center portion is included at the end.

Solving Hugs in the Rain Tessellation

  This tessellation is one I solved by Arseniy K. He called it 'Hugs in the Rain'. I referred to it in my previous post where I used the same central point, but different spacing to create my own design.  His has a much more intricate back side structure. It wasn't that difficult to figure out the architecture, however, it took a little longer to figure out how to actually execute it.  I tried the first time to fold it using thick paper and was not successful.  Second time, I tried with thin paper and it worked out pretty well.  There are a lot of layers and shapes very closely packed.  The central hexagons are open back hexes. The other shapes are grid natural parallelograms. When you fold the parallelograms you have to fold them over towards the centers of the open back hexes. The triangles are 1.5.  My first photo is what he called the back, but I really like it a lot. Especially how it back lights.  The second photo is what he designated the front.  My crease pattern is

Lazy Roulette Tessellation

 Shortly after I'd finished folding my 'Evolving Time Machines' tessellation I saw one on Instagram by Arseniy K that used a similar center point.  I created this tessellation using that slightly different central module.  The spacing between the main clusters are different from his. I used a simpler approach very much like the one I used in 'Evolving Time Machines'.  It's an all natural to the triangle grid design.  What's really nice about these sorts of tessellations is that they don't require very many additional creases after you complete the grid and they don't strain the paper much. So they're pretty forgiving to execute.  Later, I examined the reverse side of his tessellation and decided to decipher that as well. I have it mapped out. That will,  hopefully, be my next fold sometime soon.  At any rate, the crease pattern for this one is at the end of this post. 

Parallel Universes Origami Tessellation

  In the case of this tessellation I found a variant of one I'd previously folded by Arseniy K called 'Clog O Clock'. While he used rhombuses and triangles, I went with all rhombuses.  The negative spaces are open back hexagons.  All the rhombuses are on the front.  Some are fully front forward, while others must be partially reversed.  That's what creates the pattern of some darker rhombuses and some lighter ones.  You can see from the photo of the reverse side that there are no triangles at all. Which is unusual.  Still need to take a pic of the crease pattern. Will add it at a later date.  Update: added the crease pattern at the end of this post. 

Evolving Time Machines Origami Tessellation

Here's a tessellation that just came to me pretty abruptly.  While it does utilize open back hex twists, it mainly uses the natural folds of the triangle grid.  Funny thing about this particular tessellation, a little while after I'd finished it, I saw a tess by Arseniy K that was different, but quite similar.  This happens often with origami tessellations. People find patterns independent of each other that are the same sometimes and also ones that are only a little different.  That led me to solve his variant. It's was  pretty easy as they were both very much alike. I haven't folded his yet, but do look forward to doing so. The key to getting the right look on the front of this design is actually what you do on the back side.  After you've folded everything into its proper place, you still need to reverse some of the folds to cover up the hex twists on the back. That's how you get the distinctive dark twisting stars on the front.  You can see in the picture o

Folding Lava Tessellation by Daniel Kwan

Image
Last week I was having origami writer's block. I didn't have any good ideas of my own and I wasn't really clicking with solving anyone else's tessellations.  So, I decided to just fold a pre-made crease pattern to clear my mind.  This one is by Daniel Kwan. I found it on his flickr page. He called it 'Lava'.  Link to his crease pattern and models . It has a lot in common with symmetrical designs of other authors. But he uses bigger shapes and two different sizes of hexagons. There is a lot of back and forth. This shape goes up, this one goes down. It's a lot to keep straight. Sometimes using already created crease patterns can be just as tricky as having to figure one out.  But once you get the orientations sorted out in your head, the actual folding is pretty pleasant.  The finished product is pretty nice too!
