Quilt and wallpaper

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

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

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

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... I ended haven't to use my own host.

Pentagons and Triangles

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...  

Tileland+ code

Tileland+ interface

Along with an interface update, I added a some language extras.  The native Tileland instructions remain (polygons, colours, and turning) but now I have added the environment instructions to the language.  In particular, I have added clipboard manipulation instructions. Although somewhat hidden, this addition is a metalanguage or a preprocessing language.

6o4b>

6o4b>6o4b>6o4b>6o4b>

It's actually pretty simple when you see an example.  An orange hexagon with a blue square would be 6 o 4 b.  The picture below is a that with a right turn or 6o4b>.  The colour follows the shape so that it has something to colour. Doing that 4 times is just 6o4b>6o4b>6o4b>6o4b>.  Another way to make the pattern is to use the clipboard.  I haven't yet introduced a concept of a cursor yet so the clips come from the entire current code. There are 5 instructions that affect the clipboard: x, v, n, m, and q.  The first, x, simply transfers the current code into the clipboard.  The second, v, adds the first clip to the current code. The next two n and m roll the clips left and right. The final one, q, clears all the clips.  The other letter instruction, z, removes the last chunk from the current code (only really useful in an immediate situation).  So, to make the loop of squares and hexagons using the clipboard you could type 6o4b>xvvvv or cut and paste that into the code textbox. The result of either action is [6o4b>][6o4b>][6o4b>][6o4b>] -- the brackets chunk the code but do not affect the resulting picture.

The code in the Tileland+ image was produced by using 2 different clips -- this required using the n and m instructs to change the first clip back and forth.  For instance, in this code, "6o4>6p>>>4o>x 6o4>x  vvvnvmvnvmvnvv", the first two chunks make the clips and the third chunk use the two clips.  In terms of cutting and pasting sometimes it's best to start with a fresh clipboard so an initial q can make a fresh start -- so q6o4>6p>>>4o>x6o4>xvvvnvmvnvmvnvvmvnvvmvnvvv so  makes the pattern in the image.

Play around with this version of Tileland and tell me what you think.

New TileLand prototype

This thing is "alpha" code.  It's hot off the press with enough functionality to do interesting things but it's not very polished.  I added the link on the side bar so it'll be easy to access.  The programs come in graphical and textual forms which currently allows you to save your programs by cutting and pasting the text into a place to use later. I stripped down the instructions to one letter to make it more compact and uniform and ease of coding with a keyboard.  I'm sure things will change when I get the time.
There are some annoying bugs that I will fix soon: the one the is most irksome is that my collision detection has some issues that I believe are mainly occurring with triangles but I really haven't done any extensive testing...
