Opacity Changes

Image
I really like this small change. I wasn't expecting such a big difference. I was aiming to promote the octagram called the Star of Lakshmi or khatam sulayman, which is two overlapping squares following the recent descending pentagons had two overlapping pentagons. I switched back to emphasizing the square rather than the triangles and ended up with this above pattern. I quite like the details in this pattern. Probably, it doesn't actually benefit that much from the animation. Or perhaps I need to work on a different animation...

Descending Squares

Image
Unlike normal, I was able to deliver the square version of the descending pentagons quickly. There was no math to figure out. although there was one interesting choice that I looked into. The choice was to place the 45 triangles to be touching the previous square rather than the corner square. I guess it's simply a preference about complexity. I like both. The first version is a simple analogue of the descending pentagons--actually it was the original doodle on my boogie board. I find the boogie board is a great exploratory tool because of it's impermanence. Somehow it helps me focus on process rather than product. The version of the boogie board I have doesn't save any of your work and there is no erase so you are stuck with any mistakes unless you erase the entire drawing. So I am tasked with focusing on the internalizing any thing that I do that I think is important. Perhaps this is a bit of a throw back to all the time I spent with chalk and blackboards. Regardle…

Descending Pentagon

Image
You have to reload this page to see the animation ...perhaps I should put it on a bit of a repeat.  It took a surprising amount of high school math to unravel how to make this.  I guess I could have been content with just eyeballing it but that seems to take all the challenge away plus it makes it more difficult to augment later. Perhaps I should have used a better tool than Excel: maybe Geometer's Sketchpad.  Next time.  Perhaps I'll put up the square version of this pattern when I get the time.   Essentially, it's a snazzy version of starting with a pentagon and using the sides midpoints to make a slightly smaller pentagon and descending forever (or in this case 12 levels?).  The snazziness is was the time consuming part.  Computing the lighter bands took a bit of effort--more of a stamina thing rather than a difficult thing.

Octagonal flowers

Image
This pattern has a few cute things: a right and left handed version of the flower and some structures that seem a little out of place. The green flower is the left and the purple is the right. What I find more interesting is the way the 4 octagons behave between the flowers--there is a diagonal slit between them that alternates its direction.  The pentagons are just decorative but they make the white space more interesting.

Quilt and wallpaper

Image
I was going to try to get this into last month but alas February only has 28 days this year. here is a toned down copy that works for wallpaper wall (colour), wall (blue), and wall (sepia). I was a bit lazy using a tool to crop it so it's in pdf rather than svg...but my MacBook pro accepts it as my desktop background so I didn't pursue it.

from Pentagons to Heptagons

Image
I needed to do a modification to go from pentagons to heptagons: add a square between the triangles. Without the square the heptagons would intersect. I wonder how close there pentagons are....

Elegant pairs

Image
I was experimenting with the pervious post's pattern and the particular twist I was attempt wasn't fruitful but I did end up with this pattern. There two key pairs in this pattern: two purple rhombi (made with triangles) and the prominent pink/purple triangle-pentagons. I call this pattern elegant because of its fine lines: the slim dart gap between the rhombi, and the near touching pink polygons. Perhaps these fine features are also amplified by this type of symmetry.
I may have to augment my tool to help play with the colour choice and perhaps add in an easy centering tool. I guess these are less of a priority just a little of an annoyance...
Here are some png wallpapers

Nice 6-fold symmetry

Image
I like this one. Essentially, it's variations on a theme. Perhaps I add a twist and see if it will be as pretty. On a side issue, tinyurl.com/p3c6mdh/newPentTri2.svg didn't work when I put https which redirects to https://c3b8f482385fc05f71d246e2e23a26cb99a3c770.googledrive.com/host/0BwD1YaggiIIAY1gxNEJEa2JKNlU/newPentTri2.svg which needs the https. Not surprising but there certainly is a lot of details to juggle--at least when you are doing posting content on the cheap... Of course, if Blogger simply let me upload my svg files I wouldn't have to do any gymnastics...

Pentagons and Triangles

Image
Here's a new pattern.  I have been a bit too busy to post this last semester.  Hopefully, next semester I'll have a bit more time to play with patterns.  This one has a few variations that I may continue to play with...
